How do I fix a coding error that caused a 404 error on my product page?

Hello! I messed up with the code.

I was trying to change the colour of “Add to Cart” button, (I do not have theme.css code in theme in Assets, so I tried to do with Inspect option). After I chose the colour, my comp got glitched, and went back many times without saving ?‍ :female_sign: ?‍ :female_sign: ?‍ :female_sign: . So, now I can see it in my collections, but when I go to my product it shows 404 Page not found :tired_face: :tired_face:

The site is: https://www.plategy.online/products/16-colors-sunset-projection-lamp-sunset-lamp-653860246

Please, help me out. I don’t know what to do

Thanks in advance, if you are be able to help
