Looking at the debug output, the jobs look fine,...
1. 12_28_54_6810_01_video creates the video file (output: pp2_12_28_54_6810_01.265):

3. 12_28_54_6810_03_cleanUp deletes the old video file (pp2_12_28_54_6810_01.265)
4. 12_28_54_6810_04_create creates the mkvmerge tag file (pp2_12_28_54_6810__04.xml)
5. 12_28_54_6810_05_muxing muxes the new video file into an mkv: (this is where the crash occurs)

5. 12_28_54_6810_06_cleanUp deletes the tag file (pp2_12_28_54_6810__04.xml)
12_28_54_6810_07_cleanUp deletes the video file (pp2_12_28_54_6810_12_28_54_6810_02.265)
My guess is that there is some problem with the patching.
One bug (missing feature) I see is that Hybrid doesn't check atm. whether nvhsp actually creates the output as it should. (fixed that here
So my guess atm. is that nvhsp doesn't create the output file and Hybrid only notices it once it tries to use the output for muxing.
Since I can't reproduce this here since I don't own a graphic card which can encode 10bit H.265 I need more help to track this down.
-> enable "Config->Output->Container Settings->General Settings->Keep intermediate files", recreate the job, enable debug output level 9 and run the job again.
Assuming still crashes, post the debug output and I can tell you the nvhsp-call Hybrid uses. You then would need to call that call in a Windows Command Prompt and tell me the output.
