Traceback TypeError for any dvr-scan command

I'm running Ubuntu 22.04, Python 3.10.12. I installed dvr-scan via pip install dvr-scan[opencv]. Seemingly no issues during install. Now, no matter what dvr-scan command I run, e.g.

dvr-scan --help

I get the same Traceback error:

TypeError: 'numpy._DTypeMeta' object is not subscriptable

I'm unskilled in this. I'm not sure if this is some issue with importing cv2 package. I see from this issue that there might be some issue with package names (cv2 vs opencv-python vs opencv-contrib-python) so I tried pip install opencv-contrib-python but no change with the issue

Any ideas? TIA.
