Can not open or create unity projects anymore

I opened unity today to continue working on my new project, but the project selection screen does not seem to be working anymore. This is all it is showing:

It worked fine two days ago and I did not really change anything, besides me connecting and trying out my new Oculus Rift for the first time, yesterday.
It is currently not connected to my computer and this isn’t the actual editor not working, so I’m not sure if that could be the cause of it.

Has anyone else had this issue?

I can still get Unity to open by opening Scene files directly though.

Edit:
Apparently there was a similar bug in Unity 5 but the window was black.

It can be fixed by deleting the folder

C:\Users\USERNAME\AppData\Roaming\Unity\Packages
ode_modules\unity-editor-home
