I am also still having the exact Problem with an iPhone 7 (iOS 15.4.1) Xcode 13.3.1. I already have waited for 12 hours for it to finish but its still not done. This does seem to be a bug.

Has anyone submitted a feedback request for this error? I haven't been able to use my iPhone for debugging in almost a year.

Just created a feedback regarding this problem (ID: FB10026560)
