Luban 3.4.2 preview thing

I’m trying to make a marble track from thingiverse. But this time in high quality .
In Cura ( with the snapmaker provided profiles ) on 0.1 mm it slices and gives me a preview.
When i do the same in Luban it will Slice to 100% but it hangs there. It is not freezing as i can rotate the view etc. but it will show no preview.
The file is about 293 mb big. But as said cura does it good but Luban won’t.
Why is this?

Can you share your file on Google Drive or something so we can download it and have a look.

It is this one

I’ve put all the things on one bed and then on the High Quality settings.
