Could someone confirm if this flag is in fact meant to be deleted?

Yes, the issue for me was agreements that need to be signed in your developer account. Xcode 15. It'd be nice if it wasn't such a misleading error message.

It's possible that disabling source control in Xcode preferences, then reenabling it might of fixed this sporadic crash issue...

Have submitted report to Feedback Assistant but here is the crash that occurs. xcode_crash_idle.crash

same. constant crashing. Crashed Thread: 15 Dispatch queue: DVTSourceControlGitXPCClient :: Proxy Completion Queue XCode without git is borderline meaningless. In general, XCode 14.2 is so unstable for me.

Same issue in Xcode 13.3. Very fast internet. Hangs on Uploading package to Apple Services... and eventual kernel panic and whole computer crashes. M1 macbook air.
