That does not sound familiar to me.
Have you tried contacting Adobe support?
We didn't hear back from you. Are you still facing this issue?
Please let us know.
Im facing the same issue. Can anyone help me?
When I try compose anything the AE stops responding and shuts down.
Have you tried to update your version to 14.2? You can do it in the Creative Cloud app or in the Help Menu inside After Effects. Once updated, After effects will ask you to maintain preferences or create a new ones. Try to create a new preferences file.
It is already 14.2 but thanks!
