Unity Complete Editor Become Pink - Unity Editor Bug

Whole Unity Editor becomes pink, I don’t know what happened wrong with the editor.

Here is the screenshot of the editor:

I have changed Color Space settings from Gamma to Linear and all things become pink.
Linear or gamma workflow

I hope I will not lose my project data because of this.
I can’t able to find any way to change settings back to Gamma.

Hi,
You should be able to solve this by opening up ProjectSettings/ProjectSettings.asset in notepad (or whatever you have) and set the m_ActiveColorSpace to 0

m_ActiveColorSpace: 0

If it is not working right away, reload the Unity editor.
Hope this helps.
