We heard you! We have been hard at work fixing issues in the latest release of After Effects.
Updates to project loading to better handle corrupted files.
On Windows only, fixed a crash when closing a Timeline panel when After Effects is running on an external monitor with multiple timeline windows open.
With the Variable Frame Rate import fix, the frame rate interpretation for VFR footage may be different than in version 16.1.2. Camera tracking may need to be re-tracked or re-solved to match the footage correctly.
