Changed my wordpress address (url) and now blog is no longer working

i changed my blog from:

https://dageniusmarketer.com/wordpress
to
https://dageniusmarketer.com/

and now when i try to do anything in my admin panel, i get:

The requested URL /wp-login.php was not found on this server

And now my layout that i had working fine before, is no longer working. I have some plain text, basic html layout in its place now. I do not want to reinstall my whole site which i spent sooo much time designing. Pleaaaaaaaaasssssssssseeee tell me there is a very easy fix to get this fixed. I need this immediately. Thank you.
