This error doesn't happen due to use of compact, but because multiple processes are accessing the same Realm.

Even if you entire app is only use one process, we have unfortunately seen that during app upgrades some variants of Android actually have two versions of the app running at the same time, which Realm will detect as this error.

We are currently in the process of adding support for this in https://github.com/realm/realm-core/pull/6304, but until that is complete the only work-around is to try to defer opening the Realm a little bit, i.e. opening the Realm in Application.onCreate has a higher chance of triggering this.
