So that’s roughly the third of the information that I asked for, but if you want me to guess: you must have imported the Gameframe extension and script (or maybe just the script), but not gameframe_macros, so Gameframe doesn’t know what your original GUI resolution was. You could still call display_set_gui_size yourself to set it after gameframe_draw().
Android doesn’t have a concept of a window so you’ll want to un-tick the checkbox for it in extension properties.
That’s a really old GameMaker version, is this a Pizza Tower mod or something?
