Asset Folder Glitch???

Hey, I just imported my project into Unity, and after the import, I try to open a folder in the Projects Pane and all folders open at the same time, Then I try to close any folder, they all close. Is anyone else having this problem?

Also the console gave me this:

What does it mean?

I have this EXACT same problem, and I have no idea why this is happening. I just recently updated a very large project to 3.5, so I assumed it might be related to that. Does anyone have any help with this?

My workaround for now is creating a new project and dropping either into the new project to reimport. It’s a pain but it’s all I could figure to do…

Why in Gods name isn’t this fixed yet? My entire project is ruined!
