Issue submission checklist

• I report the issue, it's not a question
• I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
• I updated to the latest OpenCV version and the issue is still there
• There is reproducer code and related data files (videos, images, onnx, etc)

come here by seaching for solutions, same issue.

i definitely believe this issue was introduced in no more than 7 days, because a program i used very often will always fetch the latest version of opencv-python via pip, it was fine last week.

through this thought, i checked the release history of opencv-python library on pypi and change to the second last version of it, problem solved.

that is

pip3 install opencv-python==4.6.0.66
