Can confirm.

In debug it triggered an assert prior to BLI_polyfill_beautify in the log, but it's in pack_islands() > finalize_geometry() > add_polygon() where it stopped at BLI_assert(vert_count >= 3);

Although the script does call o.data.validate() it still did not get rid of all the invalid geometries.

Yep, it seems a convex hull is computed for an island of points, but the points all have the same position, which results in (vert_count = 1) <= 3

Are we even sure this is "invalid"/"bad" geometry?

If nothing is reported in mesh.validate(), we should first assume everything is fine with the mesh...

Seems like this broke between 54e397cc78 and 893bd37bc0, will check if I can find the commit

Since this is a regression and a crasher, will raise the priority.

OK, so technically, this is not a "real" regression, since shape_method was only introduced in e0d05da826
