Elementor Form Crash

Hi, When I am editing the page having an Elementor form, the page is crashing and becomes unresponsive. It keeps on loading for munites. Only the page is crashing, not the entire browser. I switched the theme, removed cache, tried deactivating the plugins, increased the memory limit etc etc but nothing worked.

What could be the reason as earlier a few days back it was working and all of sudden this error occurs.

The page I need help with: [log in to see the link]
