Hello, @IvanMTK,
I can understand your situation but as you can read this official Elementor documentation about this issue: https://elementor.com/help/500-error/ it is not a theme-related issue. In the article, you can read to know, why the issue appears on the site and how you can fix it.
I am sorry but this is totally independent of our theme. You can try to reach out to Elementor support for this as well.
Hope you can understand.
Regards 8Themes Team.
