Looking at the encoding calls:

"C:\WEYBPR~2\Hybrid\64bit\VAPOUR~1\vspipe.exe" "C:\temp\encodingTempSynthSkript_12_45_03_5410.vpy" - --y4m | "C:\WEYBPR~2\Hybrid\64bit\ffmpeg.exe" -y -hwaccel auto -threads 1 -f yuv4mpegpipe -i - -an -sn -vf unsharp=3:3:0.50:3:3:0.50,zscale=rangein=tv:range=tv -pix_fmt yuv420p -vsync 0  -f yuv4mpegpipe - |  "C:\WEYBPR~2\Hybrid\64bit\NVEncC.exe" --y4m -i - --fps 29.970 --codec h265 --profile main --level auto --sar 1:1 --lookahead 16 --vbrhq 1000 --max-bitrate 240000 --gop-len 0 --bframes 0 --ref 3 --mv-precision Q-pel --cu-max 32 --cu-min 8 --preset quality --colormatrix bt470bg --keyfile "C:\temp\720x480_ld3-side6_chapters_1000kbps_colored2_12_45_03_5410_04.qp" --output "C:\temp\720x480_ld3-side6_chapters_1000kbps_colored2_12_45_03_5410_05.265"

My guess the problem is that you are mixing Vapoursynth and ffmpeg filtering.
What happens if you call the encoding calls inside a command prompt?
