System Information
Operating system: Win 11

Blender Version
Broken: Blender 3.6, 4.0
Worked: never?

Short description of error
Coming from a crowd-render farm with weird machine configurations.
Blender doesn't kill the rendering if the color management files are missing.

Exact steps for others to reproduce the error

Remove the folder 4.0\datafiles\colormanagement\
Render a scene in background mode (blender -b -f 1)
The color management was silently switched to "Standard"

The expected behavior would be that Blender aborts the render if the desired color config if missing.

PS C:\Users\raimund.klink\Desktop\blender-4.0.0-windows-x64> .\blender.exe -b -f 1

Hi @Raimund58 , thanks for the report. As far as I understand, this is working as intended when colormanagement is not found. i.e. default view_transform is switched to "standard". see: colormanage_check_view_settings: - https://projects.blender.org/blender/blender/src/branch/main/source/blender/imbuf/intern/colormanagement.cc#L1158

https://projects.blender.org/blender/blender/src/branch/main/intern/opencolorio/fallback_impl.cc#L226

There is also a message in console when such case is triggered: Color management: scene view "AgX" not found, setting default "Standard".
I always get this error in lite build.

This is now rather a request to improve current behavior so closing.
