UE4Editor.exe crashes on 45%

Hello.
Yesterday I was coding some functionality with HUD widgets in C++, after completing it I’ve gone to sleep.
Today I decided to improve the functionality of the system. And… this.


Always. No matter what I do, no amatter what I do, either I’m trying to launch engine (To create a new project to test it) or either I’m trying to open an existing project it always crashes on 45%.
What might be the case for this? Any HELP??!

Start the editor from within visual studio, the debugger will break in the line the crash occurrs.

Or post the crash log here. https://wiki.unrealengine.com/Locating_Project_Logs

Also, you may want to update your engine to the latest minor release for 4.13 (which is 4.13.2). The initial releases can have a number of bugs/crashes that get fixed in the later updates.
