UE 4.10 VR Compositor has stopped working

cant start any projects in UE4.10 without getting this error message.
4.9 works fine.
even if i just start a new fps template i get the error message before the project is started.

any idea to solve this issue?

Hello MeMe,

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

Quick questions:

  1. Can you make sure that all of your drivers are up to date?
  2. Could you provide your dxdiag?

Hi there,
i reinstalled my gpu and oculus drivers right before your post.
solved the problem and 4.10 is working as it should.

sorry for any caused trouble and thanks for your time

ps: sorry, cant reply to your post
