    If your version of MacOS is Big Sur (11.7.11), then the error you are seeing is caused by an update on the 13th of July, many people are seeing the exact same error (0x0) if you are unable to upgrade your MacOS to a newer compatible version, your Office apps will go into Read Only mode, on the link below the full details on that update are provided.
