A big piece disappears after slicing

I need some assistance (I'm a 3D printing noob) 😥

I'd like to print the following piece: 9v battery cover for remote control taiyo rc vintage (from Thingiverse)

 

When I open the file in Prusaslicer I first turn it upside-down so the biggest piece is on the plate:

But after slicing it,this happens:

I have no clue what I'm doing wrong... any assistance would be greatly appreciated

RE: A big piece disappears after slicing

You'll need to zip the .3mf model and upload it here to get a better answer.  But usually when things disappear its due to thin walls, parts not attached or floating, etc. Basic issues with the part itself.

RE:

The model from Thingy is broken and needs to be repaired.  Right click it and select Fix by Windows Repair Algorithm.

And you'll probably need supports for the latch and ears.
