After Effects can't save project file, could not create the file.

Report · Oct 29, 2020

I'm using macOS version10.13.6. And I'm running After Effects CC20 v17.5. Today I've created a project and spent a lot of time on the projects. But now I can't save the project and I'm getting this warning:

PLEASE HURRY UP. If I lose this file I'll be fired.

Also, my keyboard is not working inside of the after-effects application.
