Crashed ffmpeg...

Okay, so the decoding in ffmpeg does work without issues and it is related to NVEncC.
Looking at:

NVEnc features
Codec: H.264/AVC
Encoder Engines 1
Max Bframes 4
B Ref Mode 3 (each + only middle)
RC Modes 63 (CQP, CBR, CBRHQ, VBR, VBRHQ)

MonoChrome no
FMO no
Quater-Pel MV yes
B Direct Mode yes
CABAC yes
Adaptive Transform yes
Max Temporal Layers 4
Hierarchial P Frames yes
Hierarchial B Frames yes
Max Level 62 (6.2)
Min Level 10 (1)

Min Width 145

and:

"D:\!_System\Hybrid\64bit\NVEncC.exe" --y4m -i - --fps 23.976 --codec h264 --profile high --level 4.1 --sar 1:1 --lookahead 16 --cqp 18:20:23 --gop-len 0 --ref 3 --bframes 3 --direct auto --bref-mode auto --no-b-adapt --mv-precision Q-pel --cabac --no-deblock --preset default --colorrange full --colormatrix bt470bg --cuda-schedule sync --psnr --ssim --output "K:\temp\Rita Ora - Barricades

I see no problem.

I would recommend:
a. try removing option in NVEncC to figure out which is causing the problem.
b. try older NVEncC versions
