Widget gone after crash [4.16.3]

Hey guys, today my computer crashed while i was working on a widget ( i worked a few days on it and saved a lot of times )
So after i restarted it and opend the engine again my main menu widget was gone. It’s still in the content folder but it’s not visible in the engine. I tried to reimport it but u can’t import uasset files… It’s the main menu for an online project so it’s pretty much the most importent widget in the game, All the online stuff is on it. I really hope someone knows something about it and can help me with this… :3
Have a nice day.

EDIT: Okay i found an pretty easy way to fix this. Go to Saved/Backups and look for your file. (Main Menu Widget). Take the latest save file and just copied it to the content folder. Then i replaced everything in the engine. Hope i could help everybody who had this problem. :stuck_out_tongue:
