[Urgent!] Project crashes after adding UI widgets

I was trying to implement UI widgets at my project, but after unsuccessful attempts I deleted the widgets blueprints itself and every changes I made in other blueprints, but when I tried to open the project again, it started to crash. Have no idea how to fix it. Resetting of windows layout at the project didn’t help.
