The new input system is the bane of my life, so I feel you. The input worked perfectly on my computer for my game, but not on some others, or in the browser build. After spending hours trying to find a fix, I switched back to the old input system.

yup. This project was the first time I've booted up unity in quite a few months, I tried to learn the new system so this is game has a bit of a mash up. I see the benifit of the new system especially across multiple platforms, but there's so many massive features unity drops and changes and updates on a regular basis it just gets tiring
