I sliced the object and it appears as it should with no gaps on the inside.  The model appears to be free from errors.

Load the model and set Cura up to slice and use the "File | Save Project" command.  Post the 3mf project file here.  Maybe there is a setting that is causing the problem for you.

I also noticed that if I rotate the object 180 degrees (i.e. upside-down) then it all works perfectly.

Can you post the 3D solid file. I would like to have a look at it.

I have a solid object (made sure it is completely solid in Fusion360):

 

When I slice it in Cura, the infill won't actually fill it. It leaves a cylindric empty area at the center of it:

and all the top completely empty:

I've tried with different infill patterns and densities to no avail. Ironically 100% leaves a perfectly empty area (see above), whilst 15% at least prints a tiny stick in the middle:

Any ideas?
