Hi, after opencv 4.6 i can't calibrate.
Tested on 4.10, 4.11 versions of dockers and opencv and MCcalib from source.

Picture is before interpolate. All markers detected.

charuco_corners always empty:

cv::aruco::interpolateCornersCharuco(marker_corners[i], marker_idx[i],
                                           image, boards_3d_[i]->charuco_board_,
                                           charuco_corners[i], charuco_idx[i]);

Please help.

Here is before interpolateCornersCharuco:

Thank you very much for reporting this issue. I am sorry to hear that you are facing problems with the checkerboard detection.
We are currently assisting another person that is also experiencing checkerboard detection issues.
At this point, I would recommend setting up your own Docker environment, sticking with OpenCV 4.5, and, if needed, using a slightly older commit (before the OpenCV compatibility update was introduced). I hope this approach helps resolve your issue.
To better address this problem in the latest version, would you be willing to share part of your data with us?

Thank you very much for sharing some images!
I will also need your configuration file so that I can test it.
