Endless TestFlight crash reports

I am on the latest iOS on the mini 19, and I've been harassed by iOS generating "do you want to submit a crash report" for a TestFlight app every 10 minutes or 20 minutes, so if I pickup the iPad after a few hours of standby i am being bombarded with dozens of intrusive popups which dont care if I submit a crash report or not. The pop ups have survived both the latest minor iPadOS upgrade, as well as the removal of the app itself and the removal of TestFlight too. In fact I am not even sure there was a crash, the popups appeared as soon as I had the bad idea to open TestFlight to get a new version of the app I had alreasy used for a couple of months, the Breez Lightning Wallet. Seems like an ios bug to me.
