Crash and loses styles on latest version

If it helps: I run PHP 7.4 and I deactivated all themes and plugins but when I activate Elementor Custom Skin 1.4 the site crashes.

What errors throws out?

Thanks for reply! I’ll try to reproduce it.
For fast reply you can use github.

Ok, thanks! ??

I was able to solve it: The problem was the missing post content widget in my templates… I had to re-apply it manually.
