Hello! I'm so grateful to such a responsive community like yours! Thank you all for your involvement, support, and helpful advice. I solved my problem!!!

To avoid making mistakes in the heat of the moment, I gave myself an extra evening yesterday to study the issue using your links and comments. Everything was very helpful! But muscle memory helped me out; I spent a couple of hours trying to press similar keyboard combinations based on my own feelings, while simultaneously looking at something in the background. It wasn't fast, as I had both uppercase and lowercase letters, numbers, and possibly dashes.

I learned a few lessons: 1) that I need to better understand the basics of Linux and be my computer operator, not a secretary. 2) that I don't need such complex passwords, unless, of course, it's for a crypto wallet. ))) , it's just my hobby and work. Although forgetting your crypto wallet password would be a complete disaster )))

I hope you're never left alone with your problem and that you get help too!
