Raw accel doesn't work while Apex is running
Raw accels values don't work while Apex is running. As soon as you close the game it starts working again.
Ideas

Furthermore, I don't recommend attempting to get the program working again, as doing so can potentially lead to a ban, (however you can try adjusting the in-game or Windows mouse settings instead):
Apex Legends -> In-Game Settings -> Mouse/KeyboardWindows System Settings -> Bluetooth & Devices -> MouseAlternative Windows mouse setting:
Windows Search Bar -> "Change the Mouse Pointer Display or Speed" -> Click on First Result
Neither me nor any of my friends get that error. Rawaccel is just a mouse driver with more settings that valorant pros even use on lan.
I really need it to rotate my mouse sensor because I hold it at a steep angle. Game's unplayable for me without it
Edit: Razer and Pulsar Mice have this feature included in their drivers, it's not cheating.
