I ran into the same issue and solved it by using Xcode 13.3 beta 3. I had created a bug report in Feedback Assistant with the Feedback ID FB9943776 which I have now closed.

My last test was on the last iOS 15.4 beta (19E5241a) and it seems to work fine. Will post again when the RC finishes installing.

Just tested with Xcode 13.3 RC and iOS 15.4 RC and it seems to work fine.
