Start by tracing the initialization and access of OC\Share20\DefaultShareProvider::$dbConn, then reproduce the reported failure by opening Group-Folders after the upgrade. Done means identifying the cause of the typed-property error and confirming that Group-Folders open successfully in the reported environment.
