msg in terminal: digikam.facesengine: cv::Exception: OpenCV(5.0.0)
/usr/src/debug/opencv/opencv/modules/core/src/umatrix.cpp:820: error:
(-215:Assertion failed) 0 <= roi.x && 0 <= roi.width && roi.x + roi.width <=
m.cols && 0 <= roi.y && 0 <= roi.height && roi.y + roi.height <= m.rows in
function 'UMat'
Tried to clean databases, delete recognition db or retrain data but still not
working. Regarding training data it seems linked to same error while trying to
rebuild: digikam.facesengine: DNNSFaceExtractor::getFaceEmbedding:
cv::Exception: OpenCV(5.0.0)
/usr/src/debug/opencv/opencv/modules/core/src/umatrix.cpp:820: error:

m.cols && 0 <= roi.y && 0 <= roi.height && roi.y + roi.height <= m.rows in
function 'UMat'
Note that it was working properly on all my pictures before and I didn't touch
at them prior the upgrade
EXPECTED RESULT
Face recognition tool to work
