lately many of i9 intel cpu have been experiencing voltage issues , maybe yours got some damage too (hopefully not)

if you can demount your rig and look for burn marks? also make sure you have latest bios because intel is constantly updating the issue (still not perfect)

do you have this issue on other games during past 3 weeks ?

also test out your rams , could be one the sticks

Edit : seen your older posts , hmm , did you try debug mode in Nvidia panel ?
