That's apparently a frequent problem.
Someone seems to have found a solution here, at the end of this post:

found the same issue with multiple enterprise apps once the devices were upgraded to iOS 15, specifically those apps built with manual signing in XCode.
This was resolved with the following different approaches.
- Solution 1 : We got rid of this by simply auto signing in XCode.
- Solution 2 : By using the latest code signature format.
- Step 1 : Add the flag --generate-entitlement-der under the Build Settings >> Other Code Sign Flags in XCode
- Step 2 : if applicable : % codesign -s "Your Codesign Identity" -f --preserve-metadata /path/to/YOURAPP.app , follow steps from h ttps://developer.apple.com/documentation/xcode/using-the-latest-code-signature-format
- Step 3 : Copy YOUR_APPLICATION.app into a different directory : XCode>Windows>Organizer>Right Click your project and show it in finder > Right Click on the archived project and Show Packaged Contents > Products > Applications > YOURAPP.app
- Step 4 : Compress it as YOURAPP.ipa (Don't use XCode's Distribute option)
- Step 5 : Distribute this app either through OTA or side load or through any enterprise store you might be using.
- Solution 3 : Update your mac to Big Sur and rebuild the App with XCode 13.x
You could try if any works for you.
