I've also been having this issue since the other day, as well as another one where I'm unable to test via USB ("the service is invalid"). I'm not certain these issues are related because I'm stuck on Xcode 11.3 and have been adding device support manually- although this has worked fine up until now on OS 14.
@JShroyer-Uni thanks for keeping us up to date on what you've tried and I'll do the same if I figure something out.
