Thank you for sharing the admin access.
During troubleshooting on your website's clone, I noticed that issue with the customizer screen was related to the Elementor plugin and not to the Rey theme.
This particular issue was recently discovered and is already escalated to the concerned team.
A fix for this will be included in the next batch of Toolset plugin updates, and for now, you'll find the patch and instructions to fix this at:

( this patch fixed the issue on your website's clone too, during my tests )
