Passcode Issues

Hi, 

My son has had this Meta 3 for a few months then today it is asking for a passcode to do anything. We never set up a passcode but I tried all our usual ones anyway with no success. Now I am worried that the headset is locked out because it won’t pair to the app but I DO NOT want to factory reset this thing. I can log in to account and all that is there anything I can do to get this thing working again?
