After trying to add the IPA via iMazing, an error occurs and says the integrity cannot be verified

How exactly did you install the app via iMazing? It sounds like you were trying to sideload it

There is a Quick Transfer option in iMazing, select it, drop your ipa file in there, then select App Store, and iMazing will prompt and install for you.
