realm-java: Native Realm Crashes on 4.2.0

Questions: Can someone decrypt and let me know if updating library will resolve these native crashes? I see the phrase OsSharedRealm_native in some of these logs, could it just be linked to a shared instance that has encryption? We have tried to reduce the amount of times realm could be open when not running in main instance.

Bugs: Native crashes reported in google play console. No steps to repro
