SketchUp 2025 Seeing Through Objects

I am working in Sketchup 2025 and all of a sudden when I get close to walls or objects inside my model it disappears, I’m not sure what I did to change this why it’s happening. I need help, how do I go back to modeling without seeing through objects?

Are you using the parallel projection camera? how big is tour model? do you have objects far from the origin? If you share the file we could probably check what´s going on.
