Importing PIL into Phbot Plugins

I want to get a Screenshot of my Screen with my Phbot Plugin.
Im using ImageGrab from PIL.

from PIL import ImageGrab

Since Phbot uses Python 3.8, I installed it locally. On my local python it works as it should, but when I load the Plugin into Phbot I’m getting the Error

Python Error: cannot import name '_imaging' from 'PIL' (C:\Users\X\AppData\Local\Programs\phBot Testing\Plugins\python38\lib\site-packages\PIL\

I did a clean installation of Phbot and installed Pillow(PIL) throught

pip install --target="C:\Users\X\AppData\Local\Programs\phBot Testing\Plugins\python38\lib\site-packages" Pillow

Any Suggestions? Thanks
