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.

No offense, but if you had just sat down with a pen and paper one day a week and tried to reconstruct the passwords you used at the time or the places where you saved them, you might have been a lot closer to the solution than you are now. Waiting for a vulnerability to appear in the programs you used is something you may never see.
If none of the advice in this topic works, maybe you can try something that comes out of the domain of technical experiments and is called hypnosis - with the help of such a procedure, some people can remember things that they have completely forgotten. Some will say I'm talking nonsense, but in your case you need to grab every straw that exists.
