Style in Edit Section not working

Hello.
I am using Elementor Version 2.4.4 and when I am trying to create or edit a post or page when I click on Edit Section and choose Style, all the editing sections become gray and I can not do anything unless reloading the page. but there is nothing wrong with other parts such as Layout and Advanced only “Style”.
Although my auto-update for plugins is on its more than 1 year I did not receive any new update for my plugins including Elementor, so I could not update to Version 2.9.14.
WordPress version 5.5
PHP version 7.3
There is no conflict with other plugins (checked)
Nothing changed by Enabling the Elementor Loader Method.
