Crash on starting a project

Hello guys, I was working on my project and created a new BP widget. Everything was working fine for hours. After saving and restarting my PC I got a Bluescreen and I had to restore my system. Now I got this crash every time i try to open a project, no matter what project.

Hello 3HMonkey,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. What version of the engine where you using?
  2. Just to be clear: when you say that you cannot not open any projects, does this include new, blank projects as well?
  3. Can you send me your dxdiag?

Hello 3HMonkey,

We have not heard back from you in a few days, so we are marking this post as Resolved for tracking purposes. If you are still experiencing the issue you reported, please respond to this message with additional information and we will offer further assistance.

Thank you.
