error: OpenCV(4.9.0) D:\a\opencv-python\opencv-python\opencv\modules\dnn\src\layers\convolution_layer.cpp:396: error: (-2:Unspecified error) Number of input channels should be multiple of 3 but got 4 in function 'cv::dnn::ConvolutionLayerImpl::getMemoryShapes'

(Translated using DeepL)

Expected behaviour

Normal output.

Actual behaviour

After Auto Focus Cropping is enabled
Click the "Generate" button

Steps to reproduce

• Windows 10
• x86
• 4.9.0.80

Issue submission checklist

• [√] This is not a generic OpenCV usage question (looking for help for coding, other usage questions, homework etc.)
• [ √] I have read the README of this repository and understand that this repository provides only an automated build toolchain for OpenCV Python packages (there is no actual OpenCV code here)
• [?] The issue is related to the build scripts in this repository, to the pre-built binaries or is a feature request (such as "please enable this additional dependency")
• [×] I'm using the latest version of opencv-python
  Version 4.10.0.84 also doesn't work and doesn't report any error messages

No repository file, test, or entry point is identified. Start by reproducing the Windows 10 x86 case with opencv-python 4.9.0.80 after enabling Auto Focus Cropping and clicking Generate; compare the reported behavior with 4.10.0.84. Done would require a repository-scoped diagnosis and a verified fix or clarified upstream report.
