Redirect Loop – Please please help

So i was getting ready to make my wordpress site live as its in a directory and i had it all working fine.

I used this guide https://codex.www.ads-software.com/Giving_WordPress_Its_Own_Directory
I was in the general part of the wp-admin and there is a spot where it asks what folder to point too:
This is the bit from the wordpress guide i was using”
Go to the General panel.
In the box for Site address (URL): change the address to the root directory’s URL. Example: https://example.com

Anyway i had done this and then went to change the other one but i decided to leave as was and didnt save that change(i had already changed and saved the one the guide told me)

I finished the rest of the guide and realised i had done everything right and the site was working perfectly.

Thats when it went wrong. I went back to the general tab and ACCIDENTLY saved the other change i made earlier that i realised was wrong and now i cant access my admin panel and it appears i am in a 301 redirect loop.

when i go to mybuttonbouquet/wordpress/wp-admin it redirects me below.

Please please help and i promise i will never do anything this stupid again
