Have you tried exporting your private keys or dump the private key from the console? If you can still remember your wallet address you can dump the private key directly from the bitcoin core console and import it to electrum wallet.
Once again I apologize if I get any terms mixed up, I'm still fairly new to BTC. So I have a backup phrase and my BTC address where I can see my balance with Electrum. So I don't think I have private key(s) where I believe its more hash generated unreadable.
Any solution would be great from online to software, etc just so I can send to another BTC address that isn't associated with Bitcore.
