OP didn't reply so far here again. There are some possibilites that could've gone wrong but without details from OP it's guesswork.

His Electrum isn't a genuine version of Electrum (only valid download site is https://www.electrum.org/#download, additionally you should NEVER skip to verify the authenticity of your Electrum download by checking the GPG signature
His computer where Electrum runs is infected by some sophisticated malware that was able to manipulate even a genuine version of Electrum (OP doesn't use a hardware wallet as signing device)
If OP sent coins to an address of his Electrum wallet and those coins (and likely the rest of his wallet) got immediately transfered to another address which is not under control of OP's wallet then obviously OP's wallet is compromised and someone else knows his wallet's private keys and worst his wallet's mnemonic recovery words
OP may have entered his wallet's mnemonic recovery words on some online website (being tricked to do so or simply by not knowing that this is an absolute no-go)
OP may have stored his mnemonic recovery words on an unsafe or compromised online digital device
OP may have taken a digital picture of his mnemonic recovery words and this picture got duplicated to whoknowswhich cloud storage (you have no control whatsoever what such cloud storage may do with your pictures; assume no privacy at all especially when cloud storage is for "free", lol)
OP's physical backup of his mnemonic recovery words got somehow compromised
OP has chosen his mnemonic recovery words by some crazy and unsafe and not random at all procedure
OP got forged mnemonic recovery words by some malicious actor without knowing that this is an absolute no-go

I might not have exhausted every possibility but maybe the most likely ones

OP, are you there! Can you give us the transaction ID? Can you tell us to wich address you have send the coins? Without any of the above information no one can help you and no one can figure out what happened with you.
If you want better assistance then you have to provide more information like the transaction ID an the address you wanted to send the coins to, otherwise, all we can do is to speculate about what have happened.

And op gives you the transaction id, there's still nothing we can do for him. The only reason I would want to see ops, Tnxid is to known if op is actually making this up or telling the truth. And if he's telling the truth, we still have to let him know that there's no way to help him get his funds back. What actually happened here may be that op had logged in his wallet keys into someone else's device a long time ago he didn't remember. He stored his keys online or on his device and fell for a phishing attack. Lastly I think upon creation of his wallet, he had asked someone to help him create a wallet and now the person has equal access to his funds.

Op, the only solution I can give you is that you should clean your device by formatting and reinstalling it. After that try downloading the electrum wallet from their official website (you might also have downloaded a fake). Create a new wallet and backup your keys offline in a safe place.

I sent bitcoin to my Electrum wallet on my laptop and immediately it was sent to another address I don't control. How did this happen?

Sorry for this, the Lord is your strength , we don't really know if the coin reflects in your wallet or not before it was sent to the attackers address but in addition of what Charles-Tim advised:
After formatting your pc, I would advice you follow this guide to avoid installing malware wallets Protect yourself from fake wallet software (guide) and take the consideration of jrrsparkles and be cautious of the site and software you use with your device next time.

It only means one thing

The seed or private key to the address you were sending the funds to has been compromised, and the hacker probably has a bot sniffing your account balances or any incoming transaction so that as soon as an incoming transaction is detected, the Bitcoin are spent immediately to the hacker's address.

Can you share the address the funds were sent to if you don't mind?

Use a better OS for your Hot wallets, like Linux. If you are keeping a lot of Bitcoins, use a cold wallet or a clean air-gapped device for your transactions

Since it seems it was a paranormal activity type of incident, I'd say you should first call the local authorities to feed them your 1 liner BS, to see how they would react, then come back here.
No details, 1 liner, obvious BS.

If you sent the coin and you saw the coin on your wallet, that means what I posted up there is valid. But if you sent the coin but you did not see the coin on your wallet but sent to a different address entirely, that means it is a clipboard malware. If it is a clipboard malware, you will need to format your device and follow the safety advice I included above.

But it is still worth saying that you can get cold wallet instead which will protect your coins than hot wallets. Or you can go for a multisig wallet.

How did this happen?

Apart from you, someone else got access to the same wallet/address where the funds were sent.

It could happen due to following reasons,

1. You accidentally entered your seed phrases/privkeys online and someone found it and accessed the wallet.
2. You downloaded a fake Electrum wallet that has a script to broadcast seed phrases or features to execute remotely.
3. Clipboard malware, which captures every keystroke of yours and delivers it to the attacker.
4. The attacker infects the device and stole the wallet file if it's not password-protected.

in many more ways but the point is your wallet is been compromised or the device where your wallet is installed.

To be sure of what really happened, I will advise you to go back to your system, copy an address and paste it somewhere else, and see if the address will still be the same as the one you copied earlier.

If it is not, then just say that your computer has been infected by a virus, and you will need to manually type your wallet. Make sure you check your wallet all the time to be sure that it is the same wallet you had in mind to send coins to, to which you are actually authorising a transaction.

If the PC is affected, you will need to configure the system OS, backup your valuables, and wipe the PC. Buy a new OS from a licenced distributor and get that changed, as private software is likely to come with viruses in it.

Someone knows your seed phrase or private key already and the wallet has been compromised. Do not send any coin there again. It can be through online malware attack or someone saw your seed phrase or private key backup.

Advice:
Format your device and reinstall its operating system.
You can add passphrase to your seed phrase to extend the words.

Backup your passphrase and seed phrase separately (but not together) in different locations. If you lose your passphrase, it is like you lose your seed phrase because you will lose access to your coins.

Avoid malware. Do not click on ads. Visit only the correct URL. Avoid search engines (like Google etc cetera). Avoid torrent files.

For better security and safety, use cold wallet. Or multisig wallet.

Let me get this clear, the coin went to a separate address different from the one you initially wanted to send it to before, or the coin landed on the the address and then later moved to a separate address you don’t have control over.

If the coin did not reach the address you where trying to send to in the first place there could only be one explanation, which is that your system is affected by clipboard virus which have change the address to the hackers own, and you made a mistake of not confirming the address before you completed the transaction.
