Cannot Get Passed Simple Sign Up (User Already Exists)

Hi! New User here!

I’m trying to create an account after downloading the app image and executing it, however at the Simple Sign Up page, I keep getting errors. I try to enter my email, it says “Creating Account”, then it gives “Error: Something Happened”. Then every time after the first time, I get an “Error: User already exists”.

I’d love to start getting into NextCloud but it’s stopping me right at the gate, hopefully someone can help. Thanks in advance!
