It would be helpful if you could provide the error message of your old pc's Ledger Live. Pay attention not to disclose sensitive details. Obviously never post your mnemonic recovery words or similar.
Also when i connect my HW wallet to another bitcoin wallet like Electrum or Sparrow wallet they find absolutely nothing either, apart from a small account with some dust that ledger live also finds, which i sent the bitcoin from. I am gutted . For some reason in 2019 i sent my bitcoin to this address here 19NduweV3Hn8RXHFBQ32pKwCtbP5RBKwQw
Electrum or Sparrow need to know the proper derivation path to know about the correct addresses and keys of your wallet. If you have used multiple accounts in your Ledger Live wallet then this needs to be setup accordingly in Electrum or Sparrow.
Your address
19NduweV3Hn8RXHFBQ32pKwCtbP5RBKwQw still has five UTXO that sum up to 1.54580626
BTC. I can only guess that this address is part of another account index of your wallet and therefore doesn't show up automatically unless you setup this account in your new Ledger Live wallet, too.
Could also be an issue of wallet
gap limit. I'm just dropping key words that pop into my mind regarding your problem.
My personal advice would be to always properly document the creation a another wallet's account (when created, for what reason and purpose, ...). Anyway, I don't think all hope is lost for you. Just don't do stupid things and particularly never input your mnemonic recovery words into an online website.
The only saving grace i can think of. Is that this account is a 'secret account' where you can add an extra word to your 24 word pass phrase. Which i do remember setting it up as i have it wrote down. However i am not sure i ever sent bitcoin to this. The problem is i had to recently buy a new ledger hw wallet because of the screen dimming issue on my old one. So maybe i need to set up the 25th secret word on the device propely? and by some miracle the bitcoin is in that account. i dont know how though?
To my knowledge of Ledger Live crap an optional mnemonic passphrase (that additional "25
th word"; it's not necessarily a single word, it can basically be anything) generates a whole new wallet which itself can have multiple accounts. You can't apply an optional mnemonic passphrase to a single additional account of a wallet. But I'm no Ledger and Ledger Live crap user.
I suggest you learn a bit more about hierachical deterministic wallets, derivation paths and account indices and maybe gap limit, too.
