#UE5 Crashes and model doesn't show anymore after

Hi, my Unreal Engine model crashes quite often, and every time my model doesn’t show anymore after, the whole level is just empty. There are little points left floating around, but nothing else, so I have to re-import everything again (I am working with Rhino, importing the volumes + textures into UE - for architectural purposes).

Any help is appreciated!

Can you try to import your models, then save the level straight away. After closing and reopening the editor are the models there?
