"Keep Xcode Version" vs. "Use Version on Disk"

From time to time while I'm editing code, Xcode 15.0.1 says "The file 'project.xcworkspace' has been modified by another application" asking me "Keep Xcode Version" or "Use Version on Disk". I didn't see this before 15.0.1 (or 14.1.1).

Who changed the file? What should my answer be? Thanks.

I also have this issue.

Same issue here, but it's no longer sporadic. It's almost every time that I open XCode or a simulator that hasn't been opened before. Is anyone looking into this issue? Failing to select "Keep Xcode version" results in the app crashing.
