SUMMARY
When rendering with the built-in NVENC H265 Profile, it crashes:

Qt: Session management error: Could not open network socket
[hevc_nvenc @ 0x7f7294202040] B frames as references are not supported
[hevc_nvenc @ 0x7f7294202040] No capable devices found

Creating a custom profile with the following parameter fixes the crash: b_ref_mode=0. Please add this parameter to the default profile.

Default profile (crashes):
ab=160k acodec=aac channels=2 f=mp4 real_time=-1 threads=0 vb=6000k vcodec=hevc_nvenc

Updated profile (doesn't crash):
ab=160k acodec=aac b_ref_mode=0 channels=2 f=mp4 real_time=-1 threads=0 vb=6000k vcodec=hevc_nvenc

This is with a GTX 1060 on KDE Neon with proprietary driver 535.129.03
