I have found that 5.4.2 works OK and in fact 5.5.3 seemed a bit flakey - but that may be that, unless you start TrackIR and have it active ie with the tracking actually active then 2024 does not necessarily see the TrackIR and it is not shown in the controls menu. Also if you access the TrackIR in the controls menu it seems not to like it and stops responding - any way I expect it will all get sorted in time.
