Hey,
Today I tried to open my existing unity project which uses the OpenVR Package. Opening failed with an error telling me that the package could not be loaded because the package manager timed out (error appended as screenshot).

So I tried to open the Package Manager in a complete new/ empty project. It also results in the error about package manager timed out.
I tried this with Unity 2019.1.3f1 and Unity 2019.1.8f. Error happens on both.
I’m using Windows 10.0.17763.
I already checked the proxy settings.
Yesterday it all worked fine, today (without changing anything) it crashes!
Reproduction:
- Open an empty (new) Unity Project
- go to Window > Package Manager
- after some time of loading, it says “Cannot load packages, see console”
(console error is appended as screenshot)

Someone out there knowing how to fix this so that I can continue my work?
Thanks in advance!
