This is a very good summary of the same process I’ve been through with support in the past 4 weeks about my crashing/reset issues. I’m fairly confident I’ve exhausted all practical options to isolate the problem or cause; so I believe there’s an issue with mainboard. I’m documenting my adventure here: Framework 13 AMD Hard Crashing Issue - #9 by Joris_Kurst
I was so keen to be switching to AMD, but now I’m wondering if I make the jump back to Intel?
