This wallet I created in 2017. Then Im sure I copied the private keys but I think its saved in a hard drive that is broken.
If your wallet is generated from the same pc would you mind to try to check the Electrum folder and look for wallet folder if there are two files or more inside that folder?
Because if there are two or more wallet file under that folder one of them is your wallet that is not watch-only wallet. You can reopen it with your Electrum wallet and I hope thats the wallet you are looking for.
