Why is there random code appearing at the top of my website?

This generally indicates either some code coming from the themes {{ content_for_header }} is broken, or the theme has some sort of error such as malformed html.

To test a website https://validator.w3.org/

If you recently made changes to the theme restore a duplicate/backup if you made one, otherwise try rolling back individual files that may be suspect https://help.shopify.com/en/manual/online-store/themes/theme-structure/extend/edit-theme-code#roll-back

Beyond that to fix it someone has to go through the site’s code and locate the actual source, then figure out if there’s a fix.
