Encode UHD prores 444(4)

Hi, I am trying to encode a UHD (3840x2160) video filtered with Avisynth+ and encode prores444 (or 4444) but the only thing I can get is the Prores as "YUV 8-bit 4:2:0" to work and the needed info gets lost.

This is how it looks in "External encoder";
-> "Edit external encoder profile", Command Arguments: -f rawvideo -s %(width)x%(height) -r %(fpsnum)/%(fpsden) -i - -c:v prores_ks -profile:v 4 -pix_fmt yuv444p10 "%(tempvideofile)"
Under the "video"-tab I want to use "yuv444p16le - 16-bit YUV 4:4:4" but this just makes VDUB2 crash instantly when trying to encode.
Error: Oops -- VirtualDub has crashed... Or out of memory error.

Just for test I have tried "yuv444p - 8-bit YUV 4:4:4", this gives me a green-blueish tinted image and "yuv422p - 8-bit YUV 4:2:2"
gives me a green-tinted image.

Is it even possible to encode in higher than 8-bit and 4:4:4 prores (or DNXHR) in VirtualDub2 (Build 44282)?
