Bug in Elementor and Wordpress reading settings

[hacko]

I was tring to fix some issues editing blog page with Elementor and i clicked to Setting -> Reading Settings -> Your latest Post. And they again to statick page. But all my work was gone. All Elementor elements from all pages and theme was gone. I can see from admin area Elementor editing settings, but even i update the content it never show in front page. I missed the header menu, the slider content, and the main content. I tried to delete plugins, reverse old backup, but cant igured out how to fix it. I have also and Master Hotel plugin. Also i when edit page, i see Page Builder Options but no information in front end. This Elementor now dont want to show me all rooms. And reservation plugin also. Do you have any idea how to fix it?
