Enabling a 3d renderer with the attached dataset results in an instant crash when a 3d map view is open.

I've attached the original version of the dataset. Note that it contains lots of invalid geometries, but fixing/removing these features still results in a crash with 3d renderer.

I can reproduce the crash... a temporary solution would be to switch to a projected CRS (e.g. meters as map units) - EPSG:3857 worked for me.

Also, the dataset covers quite a large area that leads to some numerical errors when zoomed in a lot, resulting in some rendering artifacts and glitches when panning.
