Mouse freezes when Steam is launched...unfreezes when Steam is closed

Greetings,
Linux and Garuda newbie but really enjoying the move to Linux as my daily driver. I'm having a strange issue with my Corsair USB mouse. The mouse stops responding when I launch Steam. Keyboard is fine, but the mouse doesn't move. I've tried changing USB plugs on the tower but no luck. When I close Steam (Alt + F4), mouse control returns. I've had similar issues with YouTube in Chromium but in that case unplugging and replugging the mouse resolved the issue. With Steam (Native or Runtime), the mouse is just dead until I close Steam. I've run pacman -Syu to make sure everything is updated.

Appreciate any assistance. Thanks!

Best,
Pharaonix
