My Website in MAMP is not loading properly

I installed my wordpress site in MAMP and changed the name of the site from https://localhost:8888/wordpress-6 to the name of my website. When logging back into the site i received an error message. Then I logged into MyPHPAdmin and changed the name back to https://localhost:8888/wordpress-6, now my website appears distorted. The theme is not appearing clearly and I cannot login into my dashboard.

What am I doing wrong?
