Applying a brush to the SVG in this state doesn't make sense to me.
Therefore, I ungrouped the SVG and did a Break Apart.

The nodes of an SVG can then exhibit all sorts of peculiarities that
could also play a role here. It's important to remember that a brush
is a shape that attempts to follow a contour. This sometimes works better,
sometimes less so.

Here some tips that may be helpful

Try to correct this by using the brush option.
(Open Edit Brush > Brush Option)

In my tries the Brush Size plays a role, try a smaller Brush size.

Try delete some of the nodes where the distortion occurs.

And in generell try to reduce the amount of Nodes by smoothing
the Outline.

@Subpath Hi! Thanks your advice. Applying a brush with tiny width gives a nice contour effect from this

to this

But in some places you have distortion.

@marce

I think the distortions might be due to sharp corners? I have no idea if
VectorStyler could improve them any further.

We should not forget that the Brush is stretched along the whole outline.

Therefore, as I mentioned before, it might be helpful to reduce or smooth the
nodes as much as possible.

@Subpath Hi! The image is a traced Tiff. With other programs, old Drawplus you get this applying a brush

With the more modern affinity you get something like this

Appear not related to an error in the svg.
I opened the SVG in inkscape, where it was originally traced, selected all the nodes and applied the "Auto-smoot" thing, and then exported it and opened with VS. But when you apply brush i get this anyway:
