Apple Sign In shows the ipa file name instead of the app name on ios15.4.1

As stated in the title, the Apple Sign In view is showing the ipa file name instead of the app name on iOS 15.4.1, unlike on previous versions when it would show the app name. It doesn't happen on any older versions, just on iOS 15.4.1. Has anyone else encountered this? Is there a way to fix/workaround it?
