Send an email to [email protected] - I think they would have to help you if all of the standard things did not work. Maybe something funky going on with your account (might also try the password reset route).
That is just a workaround suggestion since it may get your account out of some odd state on CodeWithMosh’s end. It has the advantage of being something you can do without contacting support. That being said, you may still end up having to contact support. This is just another idea you might like to try if you do not want to wait for support to help you.
