Help please: GU_OFF ?

I'm using an unmodified Planck dropshipped keyboard. It is mostly as represented here https://raw.githubusercontent.com/qmk/qmk_firmware/refs/heads/master/keyboards/planck/keymaps/default/keymap.c with the exception that the lowest-left key is 'shift' and not 'brite', although it would be nice if it were related to my keyboard backlight. See also https://config.qmk.fm/#/planck/rev7/LAYOUT_ortho_4x12, which seems to match except that both my spacebar buttons are, for now, really just space.

My toddler mashed some buttons for ten minutes before we realized where he was, and ever since then my GUI key is disabled. I have verified that it is, evidently, the GU_OFF command that was run, as it is strictly the GUI key that is disabled and even when I swap GUI and ALT (Meta) it remains the GUI key (even after it changes position) that simply does nothing. I have never installed my own firmware and mostly have just utilized the Dvorak layer. I really need my GUI key back. I've verified that it is the keyboard and not the system by using the keyboard on another, my Windows gaming box, and still there is no GUI key (there used to be, as it brought up the Windows start menu, which I used sometimes).

Any idea what could have disabled my GUI (Windows, Super) key on my Planck, and how I can get it back short of flashing the keyboard (I can't get to Flashing, but that's another post)?

After a year of hard work, I can finally share this with the world. Umineko Golden Fantasia: Community Edition enters public beta on Steam.

To celebrate it, the game is 40% off on Steam right now. Give it a go. It's pretty damn good.

Frage: bist du in einem politischen Zusammenhang, in dem schon länger irgendeiner form von männlichkeitskritik (von allen oder fast allen Männern) praktiziert wird?
Was denkst hat sich dadurch geändert?
