If you're on a Mac, this worked for me.

Close After Effects,

  • Open the Terminal and enter 

 

defaults write com.adobe.CSXS.11 PlayerDebugMode 1

 

  • Go to System Preferences > Security > Full Disk Access > Enable After Effect (Or add if not there)

Is this your first time trying to open this extension, or was it previously working correctly?

 

Almost every time I've seen someone having extension issues, they're using the wrong zxp installer. Make sure to use the one from AEScripts, as recommended.

I use Flow extensively in all versions of After Effects. I LOVE it.

As Kyle mentions below, make sure you're using the installer from aescripts + aeplugins. It's the best way to make sure it's installed correctly.
