Customizer and live editor not working

Hi
On my main website page the customizer doesn’t load , and even the live editor doesn’t work!
Want to change the button link of the main page slider , I can view the home page but when I click on Customize I just get a blank page with a messed up url

Hello there,

Please share me the page URL in question, so I can inspect whether it contains JS error or something else and probably be able to suggest the solution.

Regards,
Kharis

The page URL is http://lokaso.in/
