Hi.

I have a 2 question.

1) Do you using self build library?

2) Are you care about difference of Debug/Release library"
When you build for Debug, you must link "opencv_yyyy243*d*.lib" and when you build for Release, you must link "opencv_yyy243.lib".
"d" is important. When you missing "d" or adding unnecessary "d", will invoke mojibake or application crash.

1) Yes.

2) I link to Release library, but I also have troubles and crashes in Release mode.

You should detect which function causes the crash yourself. It is possible, that the bug in your application, not OpenCV.
