After Effects Error: Invalid Filter (25 :: 3)

Hello!

I have After Effects cc 2020 on my MacBook Pro and I had recently installed rsmb plug-in in my Mac. But I keep getting this error "After Effects Error: Invalid Filter (25 :: 3)" when I try to add it to my layer. I have also attached a picture. Please help me solve this problem as I need rsmb for my projects!!
