Mobile navigation Toggle won’t work

Hi, I’m helping a friend how has built a website with Astra theme and elementor. On a certaint point the mobile navigation toggle stopt working.
The strange thing is when we’re loggend in WordPress and visit the site the mobile navigation toggle works, but it won’t work when we’re logged out.

Now I’m looking at it but can’t find the way to fix it. I see that on the website when logged out the class won’t be loaded when I hit the Menu-button. When I’m logged in I see it happen.

Can someone help me?
