The FFF doesn't include the 3D-Model so it is hard for us to reproduce

Well it is not complete in mid-air, since the outlines are printed first

It also seems like you havent designed you model properly for 3D-Printing.
I think bridging is only triggert when all outline perimeters fit in the wall and then get filled
So I made a similar model for myself. So with a wall thickness of 1.6mm
If you make the wall thicker so that all perimeters fits in, then the infill will trigger the bridging
