I went from 16.3 to 17.1 and got error messages

Going from 15.3 to 16.3 was easy. No error messages. When I then tried to go from 16.3 to 17.1 I got errors and it restarted, but when it restarted, I was all of a sudden in 17.1. But, certain things are behaving erratically. My Snap software store, for instance, won't open at all. I had chatgpt help me out with some issues, but certain things are just wrong. Here's an error report from terminal. Errors - Google Documenten

MOST things are working fine... but the store isn't working and my preferred screenshot tool is Flameshot, but no matter what I do, the native screenshot tool takes over when I try to screenshot with flameshot. Help!
