Hi, as I can check there is no product image showing on the collection page. btw if you are getting blurry images try using small compressed images of the product item so that the WordPress does not compress on its own.

as you mentioned that your website was working fine till yesterday, I would advise you to install any “backup” plugin to back-up your work so that even if anything wrong happens to the website you can easily restore to the previous situation.
