Thanks, but this was useless information that both the website and apple support gave, I have no other physical or virtual devices or a VPN so it couldn’t have been an issue. There was a fundamental error in one of the other older updates, most likely 10.15.5 that caused the bridgeOS to be either out of date or labelled as the wrong version. Due to this, I had no choice but to reset the BridgeOS using DFU mode so that I could fix what the update broke.
