It could be a bios issue too, since not many have it. The only way to reproduce it consistently is to spike the CPU to full load and then remove the load. There are no logs, which make finding the issue even harder, but otherwise that fix works and I don’t have enough knowledge to even tackle it.
I am running a notebook with AMD 5300U and a desktop with 5900x and none has problems with sleep.
