Try latest master source code and also add --y4m in the command.

ffmpeg -i "input_video.mkv" -pix_fmt yuv420p10le -f yuv4mpegpipe -strict -1 - | vvencapp -i - --y4m --preset faster -c yuv420_10 -q 23 -o "f-yuv4mpegpipe-10b.266"

I use to have issue with y4m input: https://github.com/fraunhoferhhi/vvenc/issues/129, and it has been fixed.
