Can’t drag and drop with Elementor (No IE or Edge)

Hello,

Big problem here : I can’t drag and drop widgets on Elementor anymore. When I click and hold on a widget, it doesn’t move…

I’m not using IE or Edge, I tried with Firefox, Chrome and Brave, all of them up to date.
Elementor latest version is installed, with OceanWP up to date and WordPress as well !
I tried deactivating all my plugins, it didn’t change anything.

I can still edit the widgets that are already there, the rest works fine (drag and drop was working a few days ago), but I can’t add anything on any of my pages.

Does anybody has a clue what it could be ?
Thanks in advance and have a good day !
