Comment (by John Dury):

 I added "-extra_sei 0" and tested with the gyan 08/01/2021 binaries and it
 works! So happy. Once the 495 driver goes GA, I will try it and update but
 at least this is a working woraround for now with the latest windows
 binaries. So helpful. Thanks much.

 while. But on the other hand we bisected it (if you did not get it, my
 problem is different from his, it is -bf -1 regression due to some strange
 SEI in the very start of the sample) it is either
