After Effects Comps not opening in the project window

[Clay5FC4]

Using After Effect this morning trying to get something out asap and I double click on the comp that I want to edit and it won't open. I've restarded the whole computer etc and then created a new comp and the new comps won't open either.

Thanks for providing the file. I was able to open up the .aep without any issue. Have you upgraded your OS or GPU driver recently? Something that may have changed on the computer otherwise?
