I can't select anything except a weird shape on the right side, inside that house. If I move the select box across the screen, that shape is the only thing that gets selected.
If I try to click on any other object, nothing happens. If I switch from Material Preview Mode to Solid Mode, everything disappears except that shape, as you can see in the video. If I select the mesh I want from the scene collection on the top-right corner, nothing happens.
Please help, I don't know what to do and I need to work on my project.
