Game Crash to desktop due to Access Violations

[pvnco]

i have been experiencing random crash to desktop since july; switching to vulkan from dx11 appeared to work at first but has since resumed crashing: i have attached the .mdmp

here is some information i believe may be pertinent to the issue:

windmp shows access violations and errors in address ffffffffffffffff.

thank you to all and any who attempt to diagnose.

0xc0000005 almost always coincides with RAM instability, try disabling XMP/EXPO or reducing RAM frequency until it stops crashing. If it doesn't stop and you've tried everything else, replace the RAM.

both sticks are running at 4800mhz, is this an issue?

You would have to test by lowering it or disabling XMP/EXPO. Source 2 exposes RAM instability where other games don't.

Understood; will update with results.

profile adjusted and memtest passed; subsequent benchmarks on gpu and stresstests on the cpu yielded no results; really sort of at the limit of my understanding outside of just watching performance gauges and trying to narrow down where the issue is.
