Description

Crash, Error: Unable to open a realm at path '/data/user/0/xxx/files/geo.realm': Realm file initial open failed: Invalid mnemonic.

In our React Native mobile app, this error has started to appear for 10-15% of our users since our last release, yet we changed nothing to do with Realm in that release. Those users who get it, seem to get it repeatedly (locked out). The pattern is that a new install works fine, then when the app is launched subsequently, they get crashes on startup over and over, when Realm tries to read the file.

As its a small proportion of users, I have been unable to duplicate the error locally. So I released a new version that caught any exceptions from reading the realm file at startup and responded by deleting the file and creating the DB anew - downside is losing all the cached information, upside is of course they can still use the app. HOWEVER, I am finding that this hasnt fixed the problem.

Our Realm version 10.8.0 and has been for a long time.

Our encrypt key is static hardcoded.

Any insights appreciated. Is this familiar to anyone, or any suggestions at all really.

cheers
