UEFN freezes when opening any project

When I open a project in UEFN (it’s the same in every single one) it just freezes for an infinite amount of time. Surprisingly the app doesn’t close and it doesn’t also give any crash report. I was pretty focused on a big project and now i cannot work anymore.
I already tried to restart my computer, uninstall UEFN, verify the files and update graphic drivers. For now nothing worked and i’m not able to fix it. Hope anyone can give me a solution please :smiling_face_with_tear:
