BUG - Designer's and editor's mode not working at all after I restored a backup

Hello !
I just restored a backup from 2 days ago on my webflow website. And now I just can’t get into webflow from the editor’s and the designer’s mode. My website is still live and working (thanks god) but I just can’t do anything it just doesn’t work. I contacted the support, no answer yet, can someone help me please ? I have no idea on what to do, it has been 40min like this…
Thank you !
