Cycles Render - Textures Disappear then Crashes the Render
Needs Triage, NormalPublic

Short description of error
If I render this scene, the textures eventually start disappearing and turning pink then it crashes.

At first it renders the output just fine but eventually textures start disappearing then it crashes

Blend File and Textures Here (650MB)

How it's supposed to render

In the last few frames it renders with glitched out textures:

Then it crashes.

Even with less textures the error still happens.

This is how the render is supposed to look

Even more smaller rar file samples:

28MB
13MB

I won't repeat the description above, essentially same results even with less and less textures involved in the blend file. First 2 crash in the 80-90 frame range, smallest (13MB) crashes at around frame 130. No errors occur when there are no textures.

Exact steps for others to reproduce the error
Render the blend file above as an animation and it should start producing errors and crash at around frame 80-90.

Extra Notes
I've tried both OPTIX and CUDA and GPU only and GPU+CPU rendering and it produces the same error. CPU only rendering produces same error.

Rendering the blend in 2.92 produces the same error.

This does not happen when rendered in Eevee.

If I start the render in the frames that it glitches out on it renders the frame without error.

Rendering with "Persistent Data" option on fixes the issue but I'm not sure if it's a real fix.

Thank you for report, but provided sample file is very big. Please simplify it as much as possible by removing objects not needed to reproduce the issue.

It used to be a lot bigger because I thought reducing the number of objects and textures would fix the issue but it didn't. I will try to make it smaller and update the report.

I am unable to reproduce this issue.

Please upload sample fle directly to this site. Does this issue happen when you render with CPU only? I can't check GPU rendering.

Uploaded the smallest file to the site. Haven't tried CPU only, will try it the next time I can.

CPU only rendering produces the same error.
