Many years ago I doomed my Bitcoin and lost access to them. I have nothing left besides the locked Electrum file, a locked Zip Archive containing my private keys in plain text and my public key. I am tearing my hair out for years now. I thought I was safe if I create multiple types of storage. The Zip archive and the Electrum file have different passwords too if I remember it right. The seed is also in my Zip file since I thought I can just save it on many USBs instead of a paper. The risk of one USB failing wouldn‘t bother me.
You can save many backups but in your wallet recovery, you need access to it, and are able to decrypt these locked backups. If you fail, you can not recover your wallet, and you will lose your bitcoin.
Find someone, or a service that can help you to bruteforce passwords of your Electrum wallet file, or Zip archive file. Do it with a trusted person or a trusted wallet recovery service.
