as you can see, one side of the wall is visible, the other does not, the same occurs with the floor, ceiling, etc.
I am very grateful to anyone who can help me, thanks.

The faces of the mesh look to be inverted. Open the mesh up in a 3rd party 3d software, turn on backface cull and flip the faces of the mesh that are facing the wrong direction.
Thank you very much, never make it through this problem without your help!, Again, thank you!
