Problems deploying enterprise app (ASDErrorDomain error 854)

We are experiencing a lot of problems deploying an enterprise app for in-house use since late January. All our iPads are managed by an MDM solution. It can take 10 or more attempts to successfully deploy the app. The deployment usually fails with the message "ASDErrorDomain error 854" among other messages. The company providing the MDM solution has no idea what causes this message or what it means. I suspect the error message is not generated by the MDM solutiion but rather gets passed through from iOS. After many attempts the installation may succeed suddenly, though, and the apps works as expected, but this may take weeks. I have not done any changes to my development system. 'I am running XCode 15.3 with SDK version 17.4, the iPads are on iOS 18.3
