I can't reproduce this. Just leave commands which I used.
I'm using f68f79d.

go run --tags=bdkwallet . --utreexoproofindex --prune=0 --miningaddr=bcrt1qdacmhk864uwkv834zn8rhvxcku4mzk4uy9lux5 --regtest --datadir=$HOME/.utreexod/data --configfile=$HOME/.utreexod/utreexod.conf

go run ./cmd/utreexoctl --datadir=$HOME/.utreexod/data --configfile=$HOME/.utreexod/utreexoctl.conf generate
