There's a problem with your Revolution feature. Activate the Part workbench, select the Revolution feature then go to Part --> Check geometry. Or in the toolbar, it's the blue cone with a magnifying glass over it.
You get this in the Task panel:
It's telling you the resulting shape is invalid because it is not closed. So I went to look in the Sketch under Revolution. On one end of the sketch, you have this:(Never mind the fact the dimension text is mirrored, this seems to be a display bug)
Seemingly those two dimensions are identical at -2.23mm. Right? Wrong. If you double click on each one, you will get a dialog box allowing editing of the value, The dimension for the construction line endpoint reads -2.23475, but the dim for the vertical line endpoint reads -2.23497. This means the vertical line goes below the rotation axis. Even if it's by a minute amount this is bad, because it means it creates a self-intersecting surface, which prevents the creation of a "watertight" shell, thus preventing the creation of a valid solid.
At the other end we have the same problem, but over that, the vertical dim for the construction line endpoint is now -2.23332. It means that your construction line, which is used as rotation axis is not perfectly horizontal.
You did not listen to the advice I gave you
in your other topic.

You should have used only one vertical dimension for your construction line, and a horizontal constraint.
You should use a point on object constraint for your vertical line's endpoint at left and arc endpoint at right of the sketch. Both to connect to the construction line. Then you ensure they are coincident to your rotation axis and that you get a valid solid.
Another thing: don't leave dimensions as they are at the time of creation. Double-click on them, and round them up. At least for straight elements (for arcs it's not as important as they are only aesthetic elements). CAD is precision work. Making sure to round your values will save you trouble later (like right now). I would have rounded that 2.23475 value to 2.23.
Finally, one thing about your rounded end. Your arc as it is right now does not create a true hemisphere.
