Something on your server change the WordPress output. Could be the caching OR the Google site kit. However, none of the WordPress scripts and styles are properly loaded. Unfortunately, this is not theme related, so we can’t really help. I’d suggest deactivating all third-party plugins one by one and also consult with your hosting support.

Last, but not least – you are still using a theme version that’s almost 1 year old, but with the latest WordPress and WooCommerce versions. You’d need to update your theme and ALL of it’s plugins.
