If you can't authenticate it and Playstation can't help you regain access, I'm afraid it cannot be unlinked from your profile. To enable Cross Save you would need to link a free dummy account from Stadia to your current profile and sign in with that account in order to unlink your Xbox and Steam accounts. Create a new profile with either Xbox or Steam and then link the remaining account to the new profile. Be aware that changing profiles will cause you to lose any emblems redeemed through reward codes. The other option is to ignore the Playstation account on your profile, not use Cross Save and continue playing your accounts on their respective platforms.
Bungie cannot unlink accounts. You must be able to authenticate an account to remove it. If you cannot you will have to continue working with Sony to regain access to unlink it.
