Welcome to the community. I'm sorry to hear about this. Do you only see this issue with a specific project file? Could you open the Creative Cloud App, hold down Ctrl + Shift + Alt, launch After Effects, and select the Manage Plugins option? In the Effect Manager window, uncheck the "Only Show Third-Party Effects" option and check if there are any effects that are disabled. If that doesn't work for you, please follow the steps mentioned in this post: -effects-discussions/how-to-troubleshoot-startup-issues-in-after.... Let us know how it goes.
