Unity does not Start after 1 use

If I install a new Version of Unity, I can start it no Problem, everything works fine. If I restarted the Computer, it will not start again. If I install a new Version again then (one that was not installed before by hub) this new version will start just fine, but the one that was installed already does not. Its stuck on Loading Screen forever.

Taskmanager says "Atleast one Thread of “Unity” is waiting for Network-E/A to Finish.

is there anything in unity editor log?

Hey, its looping the following error:

Failed to get socket connection from UnityShaderCompiler.exe shader compiler! C:/Program Files/Unity/Hub/Editor/2019.2.5f1/Editor/Data/Tools/UnityShaderCompiler.exe
(Filename: C:\buildslave\unity\build\Tools/UnityShaderCompiler/ShaderCompilerClient.cpp Line: 319)

can you test running unity or hub as an administrator? (some older forum posts seems to mention that helps)

Started Hub and Editor as Admin, still same error.

i guess should report as a bug.

or are you using some vpn? then similar issue here,

Im running NordVPN too, I wonder why it works just fine for fresh installs though ? My friend is running NordVPN aswell and he does not have the problem.
