Hello,
Please check how it works when Storefront (default WC theme) is activated on your site.
Try to disable all the third-party plugins, that do not come bundled with XStore https://www.8theme.com/documentation/xstore/plugins/included-plugins/ , clear cache, and check how it works then.
Provide us with a video of the problem, URL, and temporary wp-admin access.
Regards
