Hello! I have done a fuckup with my PC and need help fixing it. I’m confused.

I can’t use programs that were downloaded via Microsoft Store, this is the error I get:

I reinstalled my PC a few days ago to start over on a clean slate so to speak as I’ve had it for around 5 years or so.

I tried to apply for a job with SSH and I think this might be where I fucked up, I couldn’t get it to work and I tried this tutorial.
I think maybe step 5 might have affected more than that file because I’m pretty sure it was after that I started to get the warnings.

I have tried repairing and resetting the apps but it doesn’t help, of course, I don’t think the error is with the program itself.

I tried to restart my computer but it didn’t help either.
