I understand that your collection pages are showing some broken codes above the product description. Typically, this is due to coding that isn't removed or replaced correctly when making edits to the theme's coding. Just to confirm, did you try to make some changes to your theme's code recently?
If so, then we'd recommend trying to roll back to an earlier version of the theme files to fix the theme's coding and doing the customization again. However, if you're still not sure where the problem is and you're using a Shopify-supported theme, then this might be something that our Theme Support team can help you with. While we’re not able to provide account-specific support via the Shopify Community at this time, we’d be happy to continue assisting you through live chat, email, or callback. Please visit the Shopify Help Center and log in to your account to create a support request.
If you're using a third-party or custom theme, then we'd recommend checking with the theme designer for support with your theme. If the theme designer isn't able to assist you, then you can consider hiring a developer to help you with a third-party or custom theme. Shopify Experts is our directory of certified developers that have experience in working with custom coding and they'll be able to assist with your theme.
