Export dxf

Export dxf does not work, it does so erratically that it’s not useful.
Using Blender 3.0.0 and the exporter addon is version 2.2.3.

Am I using the correct version of the addon?
Other suggestion?

The exporter seems to work okay for me in Blender 3.2:

Using add-on version 2.2.3 as well.

Very simple file … 6 objects.
Doesn’t work for me.
