Elementor Page Stuck on Loading Screen

Hey Everyone!

My name is Lari Hazanovich and I am new to all this subject.
I am only 2 years in all the business of WordPress and Web Marketing.
I must admit that I just love this Plugin!
It helps enormously in building a great, Responsive Website.
I encountered a problem in the 2.3.4 version of the plugin.
I need your help, my dear friends.
Specifically, I noticed that when I am trying to edit a Post Page on my site this problem occurs. It happened two days ago on a Website that I am working on, I tried to edit a Page on my Website, it went smoothly but when I went to edit further a Post Page I got the loading page of the Elementor Plugin stuck and nothing moved from there on.
But it’s quite strange because when I am trying to edit once again a normal ”Page” page on my Website, it has a slight delay in loading the page but it loads normally.
But once I am trying to edit the Post Page it gets stuck.

I really need your help, anybody who can help with the matter I really appreciate it!
