Observations
User reported a startup crash in their app. I'm including their DB files in a comment below. I can reproduce the issue in the app when I replace my db files with theirs.
The crash happens when I try to perform a write soon after app launch: https://github.com/zotero/zotero-ios/blob/90c7c31c806b80ed2b1375f9f79910f4f5e20f64/Zotero/Controllers/Controllers.swift#L315-L318.
Above lines run this code: https://github.com/zotero/zotero-ios/blob/90c7c31c806b80ed2b1375f9f79910f4f5e20f64/Zotero/Controllers/Database/RealmDbStorage.swift#L57-L62.
And the RealmDbCoordinator pretty much just initialises Realm instance with given config: https://github.com/zotero/zotero-ios/blob/90c7c31c806b80ed2b1375f9f79910f4f5e20f64/Zotero/Controllers/Database/RealmDbStorage.swift#L114-L117.
So to sum it up, it crashes on first initialisation of Realm instance which happens after app launch. Realm is not accessed anywhere else before this, no reads or writes.
