Airbnb Locked My Account Immediately After Registration

I recently signed up for Airbnb, and the moment I entered my phone number and logged in, my account was locked for security reasons. I don’t understand how a brand-new account can be flagged for security when I’m just trying to get started. How is it that I can't even access my account or use the platform I just registered for? I can't log in, can't register again, and I can’t even reach Airbnb support for help. This is ridiculous! I’m trying to make a booking, but I can’t even get past the registration stage. Airbnb needs to fix this issue immediately. This kind of problem should not happen to any new user.
