Will not open projects
I have Mac OSX 10.13.4 and after effects will not open the project in 15.1. I have to revert back to 15.0.1
I have the same issue in Windows 10. I can't open any After Effects projects, when Premiere CC isn't running. When it's running, most times it works.
After Effects (15.1.0) starts loading the project but never finishes. The progress bar fills only a little bit and then the program freezes. The GUI isn't responding anymore (waited for 20 mins). The only way is to kill AE process in the Task Manager, start Premiere and after that start AE and then open the project.
It doesn't matter if it's an old big project or a completely empty newly saved project. It doesn't matter were the project is saved (cloud sync folder or local hard drive).
