CrealityPrint 4.3.8.6984 hangs at 0% on 'model layering in progress'

I’m new to this 3D thing. Trying to run on a 2017 MacAir 8GB 2.2GHz running Monterey. Creality Print freezes when I go to preview - it says ‘0% model layering in progress’ and goes no further. Do I just need a newer machine? Other ideas?

Could try out Creality print 5:

Try Orca Slicer it runs hell fast on my old laptop.
I checked Creality Print 5.0 and I very liked the interface but It’s not released on linux yet.
