MacBook Pro 16", "M1 Pro" 32GB crashes semi-permanently (reboots)

Things were okay for a week, but now it started to crash almost randomly, with different kernel crash exceptions every time. Looks like the CPU or memory state gets corrupted.

When it gets "in a bad bood" it begins crashing very easily: GeekBench 5 run (CPU and/or GPU tests) make it crash after a couple of seconds. Also some websites cause the macbook to crash instantly, esp. on chrome or firefox.

Again, this is only when computer is in the "bad mood" which happens to be couple of times during the day.

I tried to:

run diagnostics (Cmd+D during power on) -- the diagnostics ALWAYS succeeds with "No issues found" (I run diags just after the crashes, a couple of times every day).

• work on battery on plug power -- does not matter, it may crash on both;

It looks like memory corruption (bad RAM or CPU chip) to me, but diagnostics says "No issues found" so I am lost a bit. I am thinking about returning but then I didn't find the exact incantation to make it crash so when I bring it to service I can show the sequence -- it depends on the macbook to be in a "bad mood".

One theory is maybe temperatures are impacting stability, but this happens always at room temperatures, so far.

Kernel Panics are predominately caused by hardware faults or faulty third-party kernel extensions.
