I had similar issue and it was related to a missing plugin from the common folder, used by AE and PR as a shared plugin folder.
My issue started when I got a video from work where I have flicker free installed and bought to edit at home where my flicker free was installed on the plugins folder inside AE instead of the common folder.
I just re-installed the plugin oh the default folder and ll is fine again.
OK. It’s been a couple years. Does Adobe read this? I have submitted this feature request.

It seems simple. You KNOW this project is missing filter. You KNOW the name of the filter. You clearly know where it is. Why not a find function? Why not a new color badge? Simple Data management.
Of course, I just edit for living. Not write software. 🙂
