Default built-in 3D Stars?

Subpath

If i convert the modified "Square Shape" to curve,
the result will be one Shape. Maybe thats why it works.

It also works when I drag Line through the Star
and copy and rotate the Line

@Subpath The last build contains some improvements to the shape builder tool working with open paths (and lines).
Using similar steps as @Subpath , but with Snap to Point and the Shape Builder tool: https://recordit.co/WjViOwpZid

cool, great

that offers possibilties for other Projects too

@VectorStyler
Still have problems on Win10.

@encart Send me the file, where the shape builder is not working.

Subpath

@VectorStyler

no problem so far, is working
also under Win 10

But at the very first point there is
no snap and no snap indicator
( little red circle )

Edited:
The peak of the ShapeBuilder results and the resulting oversize
was, as @Jayanta-Das wrote, because of the stroke applied to
the outside of the shape

Video: see here

@Subpath Confirm no issue in Windows 11.
I think the oversized is due to the stroke applied to the outside of the shape.

yes, your right
was probably in sleep mode
Did not realize it

But the very first point did not snap

Yes, didnot snap here also.

@encart Added the shape builder issues to the backlog as a bug.

When creating shapes with Shape builder, you may want to check the size at which you create the objects. I was having difficulty creating those triquetra knots and the shape builder was giving me some difficulties. If the shapes were too small, so if the artboard was a letter-sized paper, 8.5"x11" (22 cm x 36 cm ), difficulties were happening when the shapes were smaller than about 2" x 2" (5 cm x 5 cm).
Making the shape about 50% of the page size or bigger solved the problems for me. So you may want to investigate how scale affects shape builder, @VectorStyler, @encart.

@Victor-Vector

interesting

Will try to replicate at different size. But yes, size may affect the shape builder (and combine operations), as it affects the precision.
If you have an example with the start+lines where the shape builder fails, please send it to me.
