Elementor break since 2.7.0 to 2.7.4

Hello,

Since the 2.7.0, I got those issues on every version of Elementor:

On safe-mode:
Everything seems to be working, except when I update a post, some of my separation widgets disappear.

Without safe-mode:
The widget sidebar is working only to select widget, I can’t edit them

I tried to disable all the plugins and theme, reset permalink etc…

So I have to downgrade Elementor to previous version.

Any help please ?
