Blender crash occasionnally when rendering animation

Support Technical Support

Hello everyone !

My current project is driving my crazy with constant crashing, that I have never experienced before… When I render this project’s animations, it randomly crashes, sometimes after 5 frames, sometimes after 40.
I tried reinstalling Blender, reinstalling NVIDIA drivers, switching between studio and game drivers, nothing seems to fix it.

Sadly I can’t share the file, but here is the exception error, would anyone know where it comes from ?

ExceptionCode : EXCEPTION_ACCESS_VIOLATION

Someone ( :wink: ) posted a hint for several times…

blenderartists.org search: troubleshooting crash @Okidoki

( I know: this might be a bit saracastic…)

Do you have any simulations, physics, grease pencil, or anything else that can be baked to a cache, and have you baked those?

There are, but I don’t think they cause the issue, I tried disabling everything… In the end, the solution I found was to:

1/ Disable persistent data
2/ Render from the command line

For some reason that fixes it, but I still don’t know where it comes from :frowning:

Thanks for the help though
