Thanks for the file. This is a limitation we had in previous versions of Octane when using cryptomatte passes. If you temporarily disable the cryptomatte pass then adjust your material color, only the region will restart.
We changed the way cryptomatte is handled in 2022.1, so this is no longer an issue.
