I have spent days researching this issue and tried everything to fix the problem, to no avail.
I am playing Diablo 4 on my PC with a Razer keyboard and mouse. A few weeks ago, I noticed when I typed any of the "W,A,S,D" keys, it would move my character and I would see Xbox buttons appear on my screen. When I tried to type any word that featured those letters in the in-game chat window, Xbox buttons would appear instead and would not let me type words such as "Thanks" because it has an "a" and "s" in the word. I looked at my controls under Options in-game and tried to disable controller key bindings but it would not allow me to.
From my research, I discovered that Steam had some sort of update that is conflicting with Battle Net even though I am not playing Diablo through Steam. Google AI is saying Steam must be completely shut down before attempting to play Diablo, which did not solve the problem. I also have never had a problem with Steam running in the background before. Google AI tells me that there is no way to disable controllers through Battle Net. There is also no overlay feature to turn off in the Battle Net app settings.
This all seemed to have started when I updated my NVIDIA drivers and added Diablo 4 to my Razer Synapse. I have since deleted Diablo from my Razer Synapse after the problem appeared.
Google AI also gave me other options to try such as disabling my Xbox controller from the Device Manager even though I don't have one plugged into my PC. It also suggested I disable anything in my task manager named "Gaming Services" which I did, and that seemed to help for a few days, up until NVIDIA's new driver update. Now I'm back to square one. Now when I type "A" or "S" in-game, nothing happens. My Abilities and Skill tree won't appear and I can't type those letters into the chat window. The Xbox buttons aren't appearing anymore, but I still can't type those letters.
In my task manager, I keep seeing Xbox programs running and every time I try to "End Task" or disable them, they pop right back up. I've gone into my Xbox app and disabled it from running on start up, but I still can't type certain letters in the in-game chat window.
I am having a hard time finding this exact issue on the internet because it would seem most people are having the opposite problem of their keyboard and mouse interfering with their Xbox controller.
I would rather not completely uninstall the Xbox app from my computer as I use an Xbox controller for other games on Steam. And honestly, I'm not even sure if that would fix anything.
Any advice would be highly appreciated.
