ImportError: ERROR: recursion is detected during loading of "cv2" binary extensions. Check OpenCV installation.

Seeing a similar issue to https://github.com/opencv/opencv-python/issues/432 with opencv-python==4.6.0.66 packaged using pyinstaller==4.4. It works fine when running from source; the issue only occurs when packaged. opencv-python==4.5.5.64 works fine.

My Env:
Ubuntu 16
Python3.8
opencv-python==4.6.0.66
pyinstaller==4.4
