System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: NVIDIA GeForce RTX 3060/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.47

Blender Version
Broken: version: 3.0.0 Release Candidate, branch: master, commit date: 2021-12-01 07:55, hash: 9cec9b4d6e

Short description of error
When I used OCIO v2 config file and used Cycles for rendering with Optix, it worked for viewport rendering. But if I pressed F12 for final render, Blender 3.0 crashed when the render was finsihing.
I tried with a few scenes even if the Blender default scene still crashed. Then I tried rendering with CPU, it still crashed.
I also tried in Blender 2.93.5. It crashed again even if the render didn't start.
I downloaded the OCIO v2 config file from https://opencolorio.readthedocs.io/en/latest/configurations/ocio_v2_demo.html.

When I used OCIO v1.2 config file, Blender worked perfectly.

Exact steps for others to reproduce the error
test-ocio2.txt

Set the OCIO environment variable to the location of the test-ocio2.txt config file.
Start blender and set Cycles as the render engine
F12

I can confirm the crash at least. However, I'm unsure if that v2 config, which is noted as not production ready, is complete or not. In particular it has this comment inside of it:
# (As this is just a demo, not all the usual roles have been defined.)

Blender fails here because it is unable to find the "default_byte" or "texture_paint" Roles. The internal colorspace object is then left as null and it eventually crashes a bit later (which is arguably a bug regardless of validity of the config).

Will defer to the devs for further consideration. I'll attach the instructions for how to use the config in the next update here.

Actually I got an another OCIO v2 config file from Arnold render 5.0.0.2 for Maya 2020, It worked perfectly in Maya and Arnold render. But in Blender, it still crashed.

Here is the config file that comes from Arnold.
