Hello,

1. Could you please disable all plugins except these ones:

WPBakery Page Builder or Elementor
Woodmart Core
WooCommerce

If the problem has gone, activate the plugins one by one, checking the issue to detect which one causes the problem.

Let me know the result.

2. Sorry, but the “Remove unused CSS” option doesn’t work in most cases and not load necessary styles https://gyazo.com/59d2121eb6daf879839376b3646db615
Unfortunately, we don’t have a list of selectors to fix this since it is always individual for most of the websites.
You can either disable it or contact WP Rocket for help.

Kind Regards
