Bug Can't Create Nodes in ShaderGraph in unity 2020.1.2f1

I just installed the latest unity, I'm not sure if this is specific for this version or for all 2020 versions
but whenever I open a shader graph and click on new node, I get the following error

the popup appears with no texts at all, and I can't search for nodes, clicking arbitrarily on the arrows will eventually crate a node but I can't see what I'm clicking at

this happens on my existing projects and on newly created projects

 

Hey there, can you bug report this so our team can look into this?

https://unity3d.com/unity/qa/bug-reporting

 

Done
(Case 1270508)

 

I tried this on a mac machine, there was no bug there

 

Same 2020.1.13, HDRP 8.2, Windows 10 x64 1909

upd.: I tried delete Library folder

upd2.: I fixed this error by changing the permissions to the project directory. For some reason, there was limited access for users, although this only caused a problem with fonts.

upd3.: And the last thought, after I also did a reimport all, maybe only this was enough.

 

Hello. I'm seeing the "Cannot process a null font." message when creating my own editor UI using the new elements system. I load the font in OnEnable of my editor window and assign it to an element, and then at some point the font (whenever I load a new scene?) becomes null and the window does not render, and I get the message spammed in the console. How do I work around this? The code is

Code (CSharp):

1. queryField.style.unityFont = Font.CreateDynamicFontFromOSFont("Courier New", 13);
