Problem with siteorigin editor

I was writing a post and suddenly the editor stopped working. It doesn’t matter if I use a headline, hero or editor widget, when I clic on edit (on the widget) either live or not, the editor popup shows but hangs on loading and nothing appears.

I already tried to deactivte other plugins, erase cache…
It didn’t happen right after any update, it happened while writing, saving draft and previewing.

I would appreciate some insight about the problem,
Thanks
