17.1 crashing when rendering H.265 main10

Deliver is crashing on me if I try to encode a short piece (about 5 minutes) to H.265 Main10. happens both with an MP4 or MOV wrapper. It get's to about 20% of the render, which is from a master file in ProRes 422 HQ (so no other tasks involved) and it fails unrecoverable, I have to kill Resolve.

This does not happen when encoding H.264 under the same conditions, but that is supported by the hardware.
