After Effects cannot open files in the “After Effects Project” format
I am having the same issue as https://community.adobe.com/t5/after-effects/quot-after-effects-cannot-open-files-in-the-after-effects-project-format-quot/m-p/11836476

Not sure if this is an Adobe or Apple issue, or both. Happens in both After Effects and Premiere.
The only way to open the project is File > Open Project... from within Ae/Pr, which requires me to navigate to the containing folder from the Open dialog window. Opening from File > Open Recent > also works.
It's not a file-association issue; I've checked that.
Even dragging the aep on to the Ae icon (in Dock or app switcher) doesn’t work.
Sometimes restarting the computer will temporarily fix the issue.
A while back, I solved the issue without restarting by going to System Preferences > Security > Full Disk Access > Enable After Effects. But that isn't working anymore.
I've tried Repairing Disk via Disk Utility.
I've tried rebuilding the launch services database.
I've tried using a brand new admin user account.
I've tried pulling my hair out.
None of these worked.
(macos Catalina)
