Please check if the media-driver has been built successfully.
find media_build/ -name iHD_drv_video.so
media_build/media_driver/iHD_drv_video.so
Then compare md5sum of media_build/media_driver/iHD_drv_video.so and /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so.

I am getting the same error. I have installed MediaSDK, then cloned cva_sample and built it. Should we reinstall again?

It turned out my GPU was not Intel Integrated GPU. I enabled it from BIOS, then under Settings - Graphics became Mesa Intel® Graphics (RKL GT1) instead of NVIDIA.

You can try to update your library.
I use libmfx-gen.so.1.2.7 instead of using libmfxhw64.so.1.35. That will be no error.
