Project Crashes when going to another layer

I modelled an object on another layer, and then i moved it to the first layer, no problem. But now whenever i click on the first layer, the project crashes. i tried appending everything from that project onto a different blend file, but it still crashed.

here is the blend.

demo.blend (1.73 MB)

Everything appends successfully except ‘man and his girlfriend’. Even ‘man and his girlfriend.001’

Try again, excluding just ‘man and his girlfriend’.

it worked, thanks! :slight_smile:
