Strange crash

[Selur]

Doesn't look like the decoder, but like the encoder just crashes,...
To be use run:

"C:\Program Files\Hybrid\64bit\ffmpeg.exe" -noautorotate -nostdin -threads 8 -i "E:\TheHiddenBlade\source.mkv" -map 0:0 -an -sn -vf crop=1916:1036:2:22 -pix_fmt yuv420p -vsync 0 -f rawvideo NUL

inside a Windows Command Prompt. This should show if the decoder has any issues about around frame 115147. (Decoding on it's own should be fairly fast.)
The encoder part:

"C:\Program Files\Hybrid\64bit\x264.exe" --preset slower --crf 18.80 --profile high --level 4.1 --ref 4 --bframes 16 --sync-lookahead 24 --qcomp 0.65 --no-mbtree --ipratio 1.3 --pbratio 1.2 --qpmax 51 --no-fast-pskip --merange 32 --subme 11 --aq-mode 3 --aq-strength 0.65 --vbv-maxrate 62500 --vbv-bufsize 78125 --sar 1:1 --deblock -3:-3 --non-deterministic --range pc --colorprim bt709 --transfer bt709 --colormatrix bt709 --demuxer raw --input-res 1916x1036 --input-csp i420 --input-range tv --input-depth 8 --fps 24000/1001 --output-depth 8 --output "E:\TheHiddenBlade\2021-02-26@17_40_27_2010_01.264" -

looks fine to me.
RAM usage should be high either so that should not cause an issue.

My guess is that either:
a. the decoder has an issue with the decoding and sends some really strange output to x264 which make it crash
or
b. the encoder has some problem
or
c. there is some hardware or temperature issue.
or
d. some other tool anti virus or similar is for some reason is interfering with the encoding.

I assume your system isn't overclocked. Also do you know by any change whether it always crashes at the same position?
