Hello! Strange bug you have there, I'm using a PS4 DualShock too and it works fine. A friend of mine also tried with the PS5 DualSense (I don't have one sadly) and he said it worked fine too so I'll see what I can do but that's weird! Sorry this happened to you.
I appreciate your action!
I also experimented with remapping the gamepad controls. When I clicked on the Jump input, it immediately made the button L2 without waiting for a further input from me. I feel like the game might be registering the same button input twice for the X button on my DualSense?
Also, L2 tabs me out of the game.
