To everyone who has this issue, I just resolved it by deleting my WordPress mysql database (DROP DATABASE ‘your-database-name’;).
I then remade the database with the same info saved in my WordPress config files and the setup wizard is working like a charm. I’m using a Digital Ocean droplet so I have full back-end access; if you don’t, see if your host can reset your mysql database and/or remove all the Woocommerce mysql stuff.
