Running into the same issue here.
bench clear-cache I got to the point where it created the Accounts but then it was stuck again. Guess that's about the end. But I'm unable to complete the setup wizard.
Maybe build in a way to skip it? At least for development.
Same for just the frappe setup wizard. I ran
bench clear-cache and changed the name of the new user, twice, because then it complained that the same user already exists. After that I could complete the setup.
