Fragpunk on Linux

Hey everyone, I've finally made the switch to Linux and ditched Windows for good. Everything's running perfectly on CachyOS with Hyprland. The only issue is FragPunk—it's currently the only game I play that I can't get working properly on Linux. The game launches fine, but I can't control the mouse at all during gameplay (it doesn't move an inch), though menus work without any problems. Has anyone found a fix to get it running on Linux? Thanks in advance!
