Blender 2.91.2 crashes randomly
Closed, DuplicatePublic

Description

Operating system:
Windows 10 Pro version 2004 build 19041.804

Graphics card:
(2) 1080ti

Blender 2.91.2
Random, unexpected crashes. It suddenly closes.
It worked fine since its release but now it keeps crashing all the time. No new software added to the system and still using the same video card driver I've been using for a while — Nvidia 456.38 WHQL

Found this in the log

An update: this time the crash doesn't seem to be related to the GPU but Blender itself:

If this is purely random, this is going to be hard to triage.

does this happen in any file?
does this happen with previous versions https://download.blender.org/release/?
does it happen when you do certain things?
does it happen in other software as well?
does upgrading the GPU driver help?

Thanks for chiming in @Philipp Oeser (lichtwerk)

A few more info.
It does happen in any file.
I'm testing with other versions. At the moment, I'm actually trying 2.92 rather than previous versions but apparently, it's working fine. I'll do more tests this weekend when I free up from work.
Other software works fine with no issues (other 3d software, compositing, and motion graphics software)
I'm a little reluctant to upgrade the GPU driver as I've had system issues in the past unless I stick to the current driver (or older) which has proven to be very stable.

I'm actually trying 2.92 rather than previous versions but apparently, it's working fine

That is good to hear, please keep us up to date if issues return (otherwise this could be closed if it is permanently fixed in 2.92)

Same issue here. Files are closing randomly. The last crash log is attached. The issue started with 2.91 and still exists in 2.91.2. Haven't tried 2.92 yet.
