is it somehow below 0 Z ?
Why is this whole chunk of the model dissapearing?

Or too thin (much less than one layer height)?

Are you sure the geometry in that part is valid? From your picture it looks like your slicer is trying but failing to generate some crumbs in midair, there, but obviously that’s not right. Is it a closed shape, in that it actually has a bottom surface an edges in addition to the top surface visible there?
What slicer are you using? Slic3r and its derivatives (Prusaslicer, for one) will show a warning in the lower right corner if you have a model loaded that has borked geometry.
Also, that flat surface looks really thin. It might be thinner than one layer height, which even if you can get it to print that way it won’t come out dimensionally accurate and you’ll probably never get it off the build plate without curling it up, either.

The angle makes it look really thin, but the object is actually a centimeter or so thick.
I am getting a warning saying there is an object with no extrusion on first layer though

That further adds to my suspicion that the model for that part is broken, and it is perhaps not a closed shape. If it’s missing e.g. the bottom surface that would explain it.
Is this a model you made, or downloaded? If you made it, try re-exporting it. If you downloaded it, open it in any model viewer (you can even import .stl’s into FreeCAD) and check it over for missing surfaces, edges that don’t touch, holes that shouldn’t be there, etc.

It’s cold?

Looks like some invalid stl. Try if this helps: formware.co/OnlineStlRepair

Thank you so much! This fixed it!
