Thanks for reporting the issue. The issue is generated in the native side of the library, thus we require a native stack trace log, it looks similar to this.

Answer 2 · 2023-07-25T07:11:01.000Z

Seems to be rethrown from the JNI wrapper, so there wont be any native stack trace in the logs.

Most likely the file is just deleted when the transaction is about to be committed to storage. @Lemac In which cases do your app delete the realm file? And are you doing it through normal file system operations? In that case you could try using Realm.deleteRealm(...) to ensure that the various operations are performed mutual exclusively.
