UE4Editor.exe crashes immediately after startup

When I start the UE4Editor.exe, does not matter if via launcher or manually from the directory, as administrator or not, in compatability mode or not, it loads up to 100%, then the project selection window comes up, but it instantly freezes and then crashes silently after 1-5 seconds. In some cases I can click on a project and launch it before the freeze (the crash occurs a few seconds delayed in this case) and the editor opens up, but crashes after a few seconds as well. I could not find any crash log yet and the windows event log does not show anything either.
I am running Windows 10 Pro with an i5 4690k and a NVIDIA GeForce GTX 970.

Hi Johnnyl,

Was the editor successfully loading in the past (if so, what engine version) and this is new behavior now?

Or is this the first time you have started trying to use the editor?

Thanks

He Johnnyl,

Since we have not heard back from you in a few days we are closing this post as “resolved” for tracking purposes. However, if you still experiencing an issue with the editor crashing immediately after start up, please respond with the requested information and we will continue to investigate.

Thanks,
