Hey, sorry you're running into control issues! Most often, control binding problems like this are because of Steam's controller configuration tool interfering and causing problems - even if you aren't running the game through Steam. Before anything else, try these two options:
-Go into Steam Settings and turn off "Enable Steam Input for Playstation Controllers", then reboot steam for good measure, before launching the game
-Close Steam entirely before launching the game
If neither of those work, then it's likely a compatibility issue with the engine I'm using, Game Maker Studio 1 (specifically 1, not 2), which ceased development before the PS5 came out. If that is the case, then your best bet would be to either use a program like DS4Windows to remap the controller to something the game can recognize correctly, OR run the game through Steam intentionally as a Non-Steam Game (you can rename it, if you don't want your Steam friends to know what you're playing) to take advantage of Steam's gamepad input remapping capabilities.
Sorry again you ran into problems with this - ever since Steam introduced their gamepad input systems, it's been a constant source of frustration and headaches and there's literally nothing I can do about it as a developer. I hope one of the above methods is able to fix the problem, though!
