With 4.3.0, cuda, nvcuvid with RTX2060. I am trying to use cuda videowriter. It compiles well but throw exception at runtime in cv::cudacodec::createVideoWriter. Other cuda functions works well such as gpu optical flows and cudacodec::createVideoReader also work.

Is there anything that I missed?

As far as I am aware cv::cudacodec::VideoWriter has not worked for a long time. Only cv::cudacodec::VideoReader works.
