I had the exact same issue when I upgraded from 3.10.2 to 3.10.6.  
I also had updated my packages at the same time.  
Then none of my opencv scripts worked.

I went into Appdata/local/programs/python/python310/lib/site-packages.  
I renamed cv2 to cv2\_ORG.

I did a pip uninstall\install

and it worked. I can only think that something was cached from my previous version

I hope this works
