Had a driver update today.
And I did an export without Hardware Encoding (YouTube preset), and everything worked fine.
None of the H264 Hardware Encoding worked for me.
All of the HEVC Hardware Encoding did work for me.
I tested each one, one at a time.
Other export logs
All using the YouTube preset.

Update #2: Using the YouTube preset, none of the H264 encoding works, while the HEVC does.
