Maya 2020 Color Management Issue

[denniswP59X5]

I had a student that was having trouble with his colors. The screen was all green. I had him send me the file, and I figured out that somehow he has a corrupt because his color nodes are gone and he is missing objects. 

I back on to my computer later in the day, and I get an error message. 

"Color Management" error. "Failed to apply color management settings on file open. Failed to finalize the color transform."  

Looks like the file caused some issues on my computer. 

I have not removed Maya and reloaded because it is a shared teacher computer. It is not causing an issue on my teaching partner's login. 

Today, I received the message: "Errors occurred while reading this scene that may result in data loss. Please check the Script Editor for details." 

I have tried looking on other forum posts for the answer, but I'm lost. Any help is appreciated.

Hi @denniswP59X5 

Please make sure your Graphics card working well and drivers are updated.

[zewt]

The warnings say that the viewport isn't registered.  vp2Renderer should always be there, so I'm not sure if it's falling back on the legacy viewport?

Just guessing and not a real fix, but try turning off color management (Preferences > Color Management > Enable Color Management) and see if the problem goes away.  You don't actually want color management off, of course, but it might point to the actual problem.  I'm wondering if something like a script node changed your color management settings...

We reset the preferences. And I have not had an issue since.

My Virtual Academy student is not having as much luck. All of his colors and textures are gone. It was removing objects, but I'm not sure if that is still happening. So all of his objects are green. We had him uninstall and reinstall Maya, but that only worked for a few days. He said that it seems to be happening when he tries to add sound into the Trax Editor.
