Steps & Code to Reproduce
It's hard to reproduce this error consistently, although I do get this (and other assertion failures) while randomly clicking through the app.
Most of the Realm-related code (specifically writing) has migrated to the new Actor-isolated realm instances, using asyncWrite(_
, however some parts may still use the older method (usually just try! Realm()). Concretely, anytime a view requires a realm object, it is retrieved using the old method (on the main actor). Is it possible that this is the cause of the issue?
