terminating with uncaught exception of type realm::util::DecryptionFailed: Decryption failed

Description

A customer of my app reported suddenly being unable to launch my app. It terminates on first access of the database and it turns out that it is broken for some reason.

It might have broken during a realm migration, but this is uncertain. Newly created files work just fine. I might possibly be allowed to share the db file to a developer for analysis in private, but not in public. I tried to open it with Realm Studio as well and also tried upgrading to Realm 10.25.1, but the file still cannot be decrypted.
