Anki email address

I cannot find what email address my Anki account is associated with. I’ve tried sending reset emails to all the email accounts I have but none work. Is there any way of finding out the associated email address for my ANKI account on Anki desktop (Mac). I’m desperate to be able to login on web browser and phone but cannot currently - also worry if my laptop broke I’d lose all my Anki cards

Thanks so much in advance!
