realm-java: Incompatible histories. Expected a Realm with no or in-realm history

We get the following exception when trying to open the default realm:

This realm doesn’t use encryption(and we’ve never used it on the default realm) but another realm in the same app does use encryption.

I will attach the actual realm file that’s causing this blowup in a bit

No not possible. Up until I got my hands on the phone, the version of the app installed was non debuggable(installed from store beta) and the phone isn’t rooted

Would it be possible that the user is actually using adb pull and push back the default.realm file? (like pull the Realm file, check with the Realm browser, change some something then push it back while the app is still running). change the file through any other way without Realm involved will damage the Realm file.
