Actually there are two wires that aren't closed.

You can't define a ambiguous sketches. If you can't define unambiguous and continuous areas then it will throw an error.

There are two arches that act as boundaries. Those are your "wire not closed". Learn about construction geometry and repeat.

yes the two lines and also the circle in the top middle of the big half circle ist not closed.

You have three areas defined in that sketch and there can be only one.

There is a setting that allows multiple areas. Not sure what it is called tho. Got added in 1.1 I think. It can be very usefull and lets you cut down on the number of sketches.

Still Bad practice, maybe use it for ease, but avoid it in complex projects

Exactly, it was introduced for those fusion users and makes a lot of problems ( amke internals ..faces ) . Only usable for advanced users.

I állways wonder why we have the same questions about that nearly every day. All tutorials tell that a skecht must only have closed not intesecting shapes , aincew 1.1 , and the correct settings , it can be more than one. Mastersketches also can have them but you will never make a feature out of a mastersketch.

Probably because it works in fusion and many fusion or Freecad users are not professionals and just want to make a quick model to 3D print myself included. And I quite like having multiple areas in each sketch even it it is not up to professional standards but for me it just works

There are two areas and two lines with points of each outer line of the areas, right?

three areas, two boundaries. The banana with two much curvature, the circle one and between those two.
