 Summary of the bug:

 Any QSV encoder/decoder cannot be used in FFmpeg 6.0, which is available
 in FFmpeg 5.1.2. I have tried reinstall driver, reset BIOS, switch video
 output GPU, etc., but the issue eventually seems to be on FFmpeg itself.
 Evidences exist that, for an instance, Shotcut, a video editor using
 FFmpeg as rendering core, is no longer able to export video using QSV
 hardware acceleration after updating to FFmpeg 6.0, while OBS still wokrs
 fine using QuickSync encoder.

 How to reproduce:

 Anything using h264_qsv as vcodec will fail with "Error creating a MFX
 session: -9." Example:
 {{{
 ffmpeg -i input.mkv -vcodec h264_qsv output.mp4
 }}}
 This command works fine on FFmpeg 5.1.2, however. Full log using both
 versions are attached.

 System Info:
 - OS: Windows 10 Pro 22H2 19045.2965
 - CPU: Intel Core i3-4170
 - GPUs: Nvidia GT 1030 (Primary, monitor connected), Intel HD Graphics
 4400 (Secondary, only for video processing), both are enabled and well-
 drived
 - Intel Driver Version: 20.19.15.5171
