You deserve a prize for typing all that stuff 
For folks on tumbleweed, I’m trying kernel-longterm since on 6.13.3 I’m also seeing intermittent freezes and since this is my main gear I can’t live with it.
Hoping this is a 6.13.x issue - kernel-longterm uses 6.12 for the moment. I’ve only been using it for a few minutes, so I can’t confirm it solves the problem.
More info here:
❯ uname -r
6.12.17-1-longterm
I think/hope you can do something similar on Fedora
