System Information
platform: 'Windows-10-10.0.19045-SP0'
renderer: 'Quadro P2000 with Max-Q Design/PCIe/SSE2'
vendor: 'NVIDIA Corporation'
version: '4.5.0 NVIDIA 517.13'
device type: 'NVIDIA'
backend type: 'OPENGL'

Blender Version
version: 3.4.0, branch: blender-v3.4-release, commit date: 2022-12-06 18:46, hash: a95bf1ac01, type: release
build date: 2022-12-07, 02:06:25
Issue does not occur with Blender 3.3.2

Context
The attached blend file (contents reduced to a minimum for simpler troubleshooting) crashes while rendering in Cycles.
The file contains 2 scenes (each scene contains a single mesh): "Scene" and "canyon_blue_sky". "canyon_blue_sky" contains a simple cube.

If "Scene" uses "canyon_blue_sky" as a background scene, Blender crashes during Cycles render. The render works in Eevee.
If "Scene" does not use "canyon_blue_sky" as a background scene, the render works.

If "canyon_blue_sky" does not contain any mesh objects, the render of "Scene" also works.

System info, debug, gpu debug, and crash files are attached.
This issue is a show-stopper: Since we opened the file in Blender 3.4, hundreds of MixRGB nodes were converted to Mix Color nodes so can't revert the file back to Blender 3.3.

Thank you very much for your help with this.

I was able to reproduce crash on 3.4.0, but not in 3.4.1, so this issue seems to be resolved. Please check with build from https://builder.blender.org/download/daily/
