Hybrid Crashed! When it wants to start encoding.

The Avisynth Script looks fine:

but anyways:
1. Does the Avisynth Preview work properly?

Looking at the encoding call:

"C:/PROGRA~1/Hybrid\32bit\ffmpeg.exe" -y -loglevel fatal -noautorotate -nostdin -threads 8 -i "C:\Users\Masumah\AppData\Local\Temp\encodingTempSynthSkript_08_25_37_5410.avs" -an -sn -vf zscale=rangein=tv:range=tv -pix_fmt yuv420p10le -strict -1 -vsync 0  -f yuv4mpegpipe - | "C:/PROGRA~1/Hybrid\64bit\x265.exe" --frame-threads 3 --wpp --no-pmode --no-pme --pools 8 --log-level 2 --input - --output-depth 10 --y4m --profile main10 --high-tier --min-cu-size 8 --ctu 64 --qg-size 32 --no-opt-cu-delta-qp --tu-intra-depth 1 --tu-inter-depth 1 --limit-tu 0 --max-tu-size 32 --no-hme --me star --subme 3 --merange 57 --no-analyze-src-pics --limit-modes --rect --no-amp --max-merge 3 --no-early-skip --rskip 0 --temporal-mvp --rdpenalty 0 --no-tskip --strong-intra-smoothing --no-constrained-intra --open-gop --gop-lookahead 0 --no-opt-ref-list-length-pps --keyint 250 --min-keyint 23 --max-ausize-factor 1 --radl 0 --bframes 8 --no-weightb --no-b-intra --bframe-bias 0 --b-adapt 2 --b-pyramid --ref 4 --weightp --rc-lookahead 25 --slices 1 --lookahead-threads 0 --qpstep 4 --qpmin 0 --qpmax 69 --qblur 0.50 --cplxblur 20.0 --crf 18.00 --no-opt-qp-pps --no-rc-grain --cbqpoffs 0 --crqpoffs 0 --ipratio 1.4 --pbratio 1.3 --nr-intra 0 --nr-inter 0 --qpfile "C:\Users\Masumah\AppData\Local\Temp\test_new_08_25_37_5410_06.qp" --limit-refs 3 --rd 4 --no-fast-intra --no-ssim-rd --no-rd-refine --psy-rd 2.00 --rdoq-level 2 --psy-rdoq 1.00 --signhide --no-splitrd-skip --qcomp 0.60 --qp-adaptation-range 1 --aq-motion --aq-mode 3 --aq-strength 1 --cutree --no-cu-lossless --no-const-vbv --vbv-maxrate 0 --vbv-bufsize 0 --vbv-init 0.9 --vbv-end 0.000 --no-hrd --no-aud --info --no-idr-recovery-sei --deblock=0:0 --no-sao --selective-sao 0 --no-repeat-headers --no-temporal-layers --log2-max-poc-lsb 8 --no-fades --no-psnr --no-ssim --no-interlace --range limited --no-single-sei --no-hdr10 --output "C:\Users\Masumah\AppData\Local\Temp\08_25_37_5410_07.265"

there are tons of options so may be they renamed something again.
[b]2. What happens if you call the encoding call inside a Windows Command prompt?
