Restoring Electrum Wallet failures (due to lost password)

I have my 12 word seed, and have tried restoring the wallet multiple times - none of the recovery wallets created show anything in them, when I enter the seed I get Unknown BIP39 wordlist and selecting the Electrum option greys out the Next button. Under BIP39 I have tried every variation of legacy, p2sh segwit and native segwit to no avail, and it does not Detect Existing Accounts - even the previous recovery wallets I've already created. This is a standard wallet, not a 2FA one

All this is on an online PC so the wallets should be updating. I have checked the seed phrase, all the words in in are valid according to the 2048 word list in github. The seed phrase was originally created in Electrum, I cant understand why Electrum now wont accept it as an Electrum seed phrase

My original wallet is there, I just cant get into it as my password isnt working - is there a tool I can use to recover it?
