Plugin brakes the website

Hi guys,
Tried using your plugin, but it has broken the site’s design. Some photos don’t show up and the CSS is completely broken.
When doing the inspection, I have the following error:
Uncaught Syntaxerror: un exptected token ‘}’
The resoruce ‘…./wp-includes/js/jquery/jquery.js’ was preloaded but not used within a few seconds from the window’s load event. Please make sure it has an appropriate ‘as’ value and it is preloaded intentionally.

I’m using WP-ROCKET.
I tried turning on ‘bootstrap’ option to see if it makes any difference but no.
Also , cleared cache on both CF and site and used private browsing to make sure the problem is from the plugin.

What do you think?
Thanks!
Daniel
