Some objects not showing up in final build

One of my planes is not showing up in my final build. Help please!

This can be due to a variety of reasons. Please provide some screenshots. However, firstly make sure that in project settings window, under player settings → player → resolution and presentation, enable ‘32-bit display buffer’ and enable ‘disable depth and stencil’.

If that doesn’t solve it, it might also be a problem with the textures used in the game itself which might not be supported by the device being tested on.

It worked after I restarted my computer. I guess it was a problem with the computer.
