Unsure why that'd be unless there was a controller connected, as I'm not using anything out of the ordinary to read keyboard inputs (just Game Maker Studio's built in keyboard_check functions); I've never heard of that being an issue before- going by your username, are you using Wine or anything along those lines?
OK so it ignores the keyboard if the controller is connected. Got it. Thanks
In the main menu there’s a toggle for prioritizing controller/keyboard to turn that off, allowing keyboard to be preassigned for P1 regardless of a controller being connected on start up as well if that’s preferred
