iOS 15 crash on MDM-Devices: "exhausted real (wall clock) time allowance of 20.00 seconds"

Since iOS15 most of our Enterprise-Apps do not launch anymore on MDM-devices. All fine in latest iOS14.

Any idea why that happens? I guess it has something to do with the amount or size of included frameworks...maybe.
