I search online over, but I can't find ansower, please give me a favor, think you very much.

Steps to reproduce

#include <opencv2/opencv.hpp>

#include

using namespace std;

using namespace cv;

int main()

{

Mat src = imread("D:/windows_tool/dask_background/test.jpg");

imshow("input", src);

waitKey(0);

destroyAllWindows();

return 0;

}

Issue submission checklist

I checked the problem with documentation, FAQ, open issues,

Issue 2:

Detailed description

When trying to link my minimal application to the official OpenCV windows build,

I get errors when running the application:

Also tested with build from source from 4.5.2 and from the master branch

Steps to reproduce

Calling imshow(...) seems to produce the error.

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 solution

I updated to latest OpenCV version and the issue is still there

There is reproducer code and related data files: videos, images, onnx, etc
