After effect lugging / crashing after creating a shape/ video attached

Thanks for sharing the video. I don't see After Effects crashing. However, I do see an issue with the preview. Try clearing the media cache (Edit > Purge > All Memory & Disk Cache). If that doesn't help, try running After Effects in Safe Mode: https://adobe.ly/3XNquZR

Let us know how it goes. Moving this thread from Bugs to Discussions for troubleshooting.
