System Information
Operating system: Windows 11
Graphics card: NVIDIA GeForce RTX 4070 Ti SUPER/PCIe/SSE2

Blender Version
Broken: 4.2.1 LTS, branch: blender-v4.2-release, commit date: 2024-08-19 11:21, hash: 396f546c9d, type: Release
Worked: Couldn't try earlier versions because of addons/scene compatibility
Short description of error

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.

Exact steps for others to reproduce the error
I can not share the full file right now as it is quite heavy and uses a couple of addons, but I will try to reduce it to a simple file that still crashes... In the meantime I was wondering whether some people who are more comfortable with Blender logs could identify the issue thanks to the crash report.

Here are the lines that seem to outline the crash (full files are linked to this ticket) :

Hi, thanks for the report. From logs, crash seems file specific. In your file, some link libraries are also there. Could you attach simplified version of file where crash can be reproduced?

BTW, how much RAM/VRAM system have? And how much is utilized during the render?

Hi, thank you for the reply. I do have quite a few linked libraries indeed. I spent hours disabling and enabling collections in order to find the culprit, but I didn't get any result, as the project can sometimes render hundreds of frame before crashing, which makes it very impractical, if not completely impossible to figure out...

I have 64 GB RAM and 16 GB of VRAM, and the renders' memory is generally around 15 000M. VRAM limitation was my first instinct, but I managed to reproduce the crash even on a simplified version of the scene, with barely 10 000M of memory being used.

I really can't justify spending more days on this, sadly, but I have found a solution that seem to work so far : rendering through a command line, without interface, no crash occurs

Thanks. Image editor redraw triggered the crash, that suggests why command line interface is working.
Possibly mesh.runtime->batch_cache has garbage memory.

I managed to reproduce the crash even on a simplified version of the scene, with barely 10 000M of memory being used.

Can you share logs and .blend of above?

Run following script to validate if any mesh data is corrupted (likely unrelated as command line render is good)?
Check console for error(s): Window > Toggle System Console

for ob in bpy.data.objects:
    if ob.type == "MESH":
        if ob.data.validate():
            print(ob.name + " corrupted")
