Hi, thanks for the report. I'm not able to repro the crash.
Is that with default (Draw) brush stroke?
We've a long standing bug report of Multires Displacement Smear brush. Are you using that? see: #86114 (Multires Displacement Smear brush + Dyntopo Error)

Module : nvoglv64.dll

Similar crash report I saw yesterday in which log files pointed to same nvoglv64.dll module: #98784 (Sculpting template crash)
@JosephEagar, can you confirm?

The crash happens with any brush stroke including Draw. And it happens 100% of the time.

I can confirm here again. The crashing stack is the exact same as https://developer.blender.org/T98842#1373858

I think Dyntopo is just the victim of the pbvh/drawing code misbehaving in this instance too but will leave the decision to merge into the other report to the devs.

@PratikPB2123 This seems to be fixed in today's build. If the rest of related issues are resolved too, I guess you can go ahead and close this up. Thanks.
