The lines and text indeed are in your resulting pdf but are very, very thin. You can see them when you zoom in very close. As you stayed with the default line width of 0.00 mm it is displayed as a hairline, and relative to the large sheet size it almost disappears. So change the line width to at least 0.5 mm or more.
As all lines and text are on layer 0 go into the Layer List and edit the layer attributes of layer 0 to a line width of at least 0.5 mm.
Still it is awkward that your file is multiple times larger than mine. What is your OS and LibreCAD version?
