So recently, every game that uses data stores started having these kinds of errors for absolutely no reason:
21:53:51.854 DataStoreService: OperationNotAllowed: Data Store operations blocked while running on a Personal RCC to prevent possible data corruption. API: UpdateAsync, Data Store: Test - Studio
21:53:51.859 [ProfileStore]: DataStore API error (STORE:Test; KEY:Player_1863746978) - 509: Data Store operations blocked while running on a Personal RCC to prevent possible data corruption - Server - ProfileStore:425
Expected behavior
It should work fine as it did for yesterday and so on.
