    Hello, Thank you for posting in Q&A forum. From Windows aspects there's very few insights, to further figure this issue, you will need to enable the logging by code. Insert logging statements to track the flow of your code and to print related information. You can use the OutputDebugString function to output messages to the debugger and further check it.
