Gallery (Slideshow) Drag and Drop not working after update

Hello,
after the update 10.5.1 of jetpack, suddenly on editing posts the gallery stoped working the drag n drop feature.

I’m trying to:
1) Enter to edit a post
2) Click on edit on SlideShow block
3) Try to drag and drop an image of collection and nothing happen.

On console i don’t see any error or something else.

An tip, help with that?
