[HELP] Can't convert video to HEVC

[Selur]

Hybrid is calling:

"C:\Program Files\Hybrid\64bit\ffmpeg.exe" -y -loglevel fatal -noautorotate -nostdin -threads 8 -ignore_editlist true -i "D:\2023-02-2 - PT.mp4" -map 0:0 -an -sn -color_primaries bt2020 -color_trc bt2020_10 -colorspace bt2020nc -color_range tv -pix_fmt yuv420p10le -strict -1 -vsync 0 -f yuv4mpegpipe - | "C:\Program Files\Hybrid\64bit\NVEncC.exe" --y4m -i - --fps 60.000 --codec h265 --profile main10 --level auto --tier high --sar 1:1 --lookahead 32 --output-depth 10 --multipass "2pass-full" --vbr 3600 --max-bitrate 800000 --gop-len 600 --strict-gop --ref 3 --bframes 3 --bref-mode middle --no-b-adapt --mv-precision Q-pel --cu-max 32 --cu-min 8 --preset quality --colorrange limited --colormatrix bt470bg --cuda-schedule auto --psnr --ssim --output "C:\Users\Lemenus\AppData\Local\Temp\2023-02-2 - PT_1_2024-02-28@10_56_13_5810_02.265"

and according to the log it's not NVEncC that is crashing bug the ffmpeg call.
Does calling:

"C:\Program Files\Hybrid\64bit\ffmpeg.exe" -y -noautorotate -nostdin -threads 8 -ignore_editlist true -i "D:\2023-02-2 - PT.mp4" -map 0:0 -an -sn -color_primaries bt2020 -color_trc bt2020_10 -colorspace bt2020nc -color_range tv -pix_fmt yuv420p10le -strict -1 -vsync 0 -f yuv4mpegpipe NUL

in a Windows command prompt, show any errors? (call seems to be fine, at a first glance)

Side note:
Since you don't use Avisynth or Vapoursynth, enabling "NVEnc->Hardware->Only use encode" would tell Hybrid to only use NVEnc, which might work as a workaround. (still knowing what's causing the issue with ffmpeg would be interesting)
