I have an issue with the main menu on my site.

Dear Developers,

I have an issue with the main menu on my site.
I used Elementor theme builder to create the menu, and something is causing it to not show up correctly. I cannot pinpoint a specific event that could’ve caused it to malfunction.

It’s basically a horizontal “WordPress Menu” block, justified to the right side of the screen, and on mobile it automatically switches to a hamburger menu – at least it should look like that, but instead it’s vertical and shows up weird on the users’ end. In the Elementor editor it looks just fine.
The screenshot is attached and the login is the following:

Could you help me with this problem?
Thank you very much in advance.

Best Regards,
Gergo
