Tried your preset, getting same issue.
Would be nice if a dev could take a look, this part from the logs is what I can see is where the issue starts.

[libvpx-vp9 @ 000000000072d360] Additional information: rc_twopass_stats_in.sz indicates truncated packet.
I really don’t get it, because the parameters it’s sending are the exact same parameters it sends for the first pass or other outputs when I don’t do dual pass.
Here’s a log output from a single pass output.
