Sometimes

Description

We've been seeing a non-trivial amount of crashes (1000+) in Crashlytics:

Libre3/RealmDatabase.swift:124: Fatal error: RealmDatabase: Failed to get a Realm object, key size=64, error=Error Domain=io.realm Code=3 "Failed to open file at path '/var/mobile/Containers/Data/Application/BB17F8F2-01AA-4604-8791-F8E251DDD8E3/Documents/trident.realm.lock': Operation not permitted" UserInfo={Error Code=3, NSFilePath=/var/mobile/Containers/Data/Application/BB17F8F2-01AA-4604-8791-F8E251DDD8E3/Documents/trident.realm.lock, Error Name=PermissionDenied, NSLocalizedDescription=Failed to open file at path '/var/mobile/Containers/Data/Application/BB17F8F2-01AA-4604-8791-F8E251DDD8E3/Documents/trident.realm.lock': Operation not permitted}

We've not seen this issue on our end in testing. Note we do write to our DB from the background when our CGM app gets a reading via BT.
