Premiere Pro plug-in won't import

I've been using the creative impatience feathered crop plug-in for a while now. It worked on my intel core iMac, but when I try to import it into Premiere Pro on a new Apple M1 iMac I keep getting an error message telling me "requested file could not be imported". I've asked the Creative Impatience for the most recent version of the plug-in which should work for both Intel and Apple Silicon, but when I try to import I still get the same problem.

Is there any alternatives to this plug-in or a possible solution that I might be missing?
