I do not think you have done anything wrong, look like it is associated with this post https://www.gimp-forum.net/Thread-Brush-problem--5967 and this bug https://gitlab.gnome.org/GNOME/gimp/-/issues/5509
What you can try is trim the brush into a circular shape so that edge rotation is negated. your trimmed brush attached. Use a small brush spacing, you still get boundary change edges but not the black pixels. Try working at a higher precision than 8bit - might help.
