C2 and twin3 crashing on reaper

Hi, recently reaper closed itself three times in a row for me, the actual timing when it happens seem random.

Looking at event viewers, apparently it was caused by pro-C2 and twin3, I put the logs at the end of this message

I've seen some forum posts mentioning it might be GPU drivers issue, my GPU is RTX 3090 with studio drivers version 560.81

I'm on windows 11. Everything was installed around 3 weeks ago (08/08), and the crashes have not yet happened until today.

I have not yet tried "obvious" fixes like reinstalling the plugins or running reaper with integrated GPU, but I will update as/if the issue continues.

after an entire day of debugging

it was bad ram sticks..... replacing them fixed everything

I have 0 clue why it only ever shows fabfilter plugins causing the crashes (from only C2 and twin to volcano saturn pro-L and pro-R as well)
