What to do now? How do I convert an "unconfirmed parent" transaction" to Local? I think it has to do with the server I'm connected to, I tried to change it but I couldn't get the same result
Yes, the first incident simply happened because the parents of the parent transaction of your "screwed_TXID"
happened to have a very low transaction fee that got it dropped from your (auto-)selected Electrum server's mempool, that dropped all of its children txns as well.

During that time, the unconfirmed parent should've been dropped as well since it's the reason why the "screwed_TXID" with higher fee rate was dropped.
But now that the average mempool size is low, it's now propagated to the network again that reverted it back to "unconfirmed parent".

If i dont do this, I cant spend the confirmed inputs. What to do now?
If you're talking about 4566c3cfc229a494be03fb2811e4ebdb2052342ddfec0ea720217068d4e546c5:
Manually remove that transaction while offline (you can try it while online using v4.5.4) using the command: wallet.adb.remove_transaction("TXID")
After the transaction is removed, the UTXO list in the 'Coins' tab should be updated to what it was, use 'Coin Control' to select only the confirmed ones then send.

what about the other input (the confirmed UTXO used on the transaction, address ends in avh5). Can it be spent on a different transaction?
I saw that you've already did that which replaced the mentioned "screwed_TXID" in the OP, it's now confirmed.

Not only that, this screwed_TXID has now some descendants because the change address of screw_TXID was used for another transaction (for some reason, the wallet of this entity thought it was a good idea instead of using available UTXO's to forge that transaction)
Since you did replaced it, those descendant transactions are now dropped from mempools.

If you do not want the client to spend unconfirmed UTXO in your next transactions (in Electrum as hinted in the OP),
Tick the setting "Spend only confirmed coins" in the settings icon [https://www.talkimg.com/images/2024/04/25/rUBEz.png] of 'New Transaction' window (After clicking "Pay...").

I managed to spend the confirmed UTXO (ending on avh5) that was part of the screwed_transaction. How? Well, on Electrum the status was "Unconfirmed parent" but for some reason it suddenly changed to "Local", so I click "remove" and it "reverted the broadcast of the screwed_TXID" and I could select the confirmed input (avh5) to use it on a different transaction. Now, I went back to Wallet A where the unconfirmed UTXO (ending on 86t) part of screwed_TXID  originated, the thing is I can't manage to do the same (convert an "unconfirmed parent" transaction to "Local"  to spend only the confirmed inputs). If i dont do this, I cant spend the confirmed inputs. What to do now? How do I convert an "unconfirmed parent" transaction" to Local? I think it has to do with the server I'm connected to, I tried to change it but I couldn't get the same result

As part of an RBF? Definitely. As long as the nSequence of the transaction input does not indicate that RBF is disabled - and even then this would be irrelevant with mempoolfullrbf - you can create a new transaction with just this input and a higher fee and it would've been placed much higher along the tip of the mempool and hence confirmed faster.

Hello. Take a look at this transaction: 27ef035cbeb7c35424aabde6b62a0517b680f48d99bdbe8b95cb877d094fac08

The effective fee rate of the provided TXid is 21.3sat/vb, and the current required fee for the transaction to get included in the block is around 60sat/vb.

Since the parents has too many inputs CPFP will be too expensive so just be patient for the fee to drop or the TX get purged and ask the sender to send with higher fee if it's dropped from mempool.

Hello. Take a look at this transaction: 27ef035cbeb7c35424aabde6b62a0517b680f48d99bdbe8b95cb877d094fac08

Two inputs, both belong to the same entity. The thing is, transaction have been pending because one of the inputs (address ending on z86t) is an unconfirmed UTXO with many unconfirmed ancestors.  (let's call it the "screwed_TXID")

What should this entity do to confirm the previous ancestors? The farthest ancestor (I think it's 837513064d77a7afafa7f67ce6f63d1fa3e435539fa72dc11a78ad6f453cca4a) is an uncofirmed coinjoin, so paying to speed it up it's not an option because it's a large transaction. (viaBTC charges like 2000$)

Also, is the other input (ending on avh5) screwed up too? That's a confirmed UTXO but since it's involved with a non-confirmed UTXO in an already broadcasted TXID the entity can't "spend it" on a different transaction (well,  at least not from Electrum, not sure if it's possible from a different wallet)

Not only that, this screwed_TXID has now some descendants because the change address of screw_TXID was used for another transaction (for some reason, the wallet of this entity thought it was a good idea instead of using available UTXO's to forge that transaction)
