Compatibility problem Polylang and Elementor PRO

Hello,

On my site in development I’ve came across a problem where if there is a form from Elementor on any of my sites the site doesn’t show up when I try to view it.
If I disable Polylang or remove the form field the site shows up normaly.

I’ve tried:
– updating all themes and plugins
– using default wordpress themes
– reinstalling plugins
– adding no action after submit on form
– configuring the form

Plugins installed:
– Elementor
– Elementor PRO
– Polylang
– Polylang Connect for Elementor

Wordpress theme:
– Generate press

Thanks in advance,
With regards,
Jernej
