Hello,
1/ In browser console next errors – https://prnt.sc/ckBbfJLrCZ_T – read this post https://crunchify.com/how-to-fix-access-control-allow-origin-issue-for-your-https-enabled-wordpress-site-and-maxcdn/ , contact your hosting provider and ask about assistance. 2/ Try to disable all the third-party plugins (including cache plugins), that do not come bundled with XStore https://xstore.helpscoutdocs.com/article/36-included-plugins , clear cache of browser, and check then. Maybe one of the additional plugins is a reason for another amount of problems. 3/ Let us know the results.
Regards
