[Bug] Crash while using material editor

I get this randomly while adding nodes, I’ve gotten it a few times in the past 15 minutes and loose all my work that is unsaved as the editor just exits.

I attached a screen of my last save in my material

, which I am rebuilding after loosing it the first time.

Shader Compiling thread exception:
ShaderCompileWorker crashed!
Unhandled Exception: 0x00000001
Couldn’t delete input file, is it readonly?

Hi Alex,

I am attempting to look up your crash report on our servers, but I will need some details. Can you tell me the name of the project you were in when receiving this crash? Also, what time and date? Once I have the report on our end, we can move ahead with rectifying the issue.

Thank you,

Alexander
