Handles a NullPointerException in Minecraft 26.1 preventing it from starting on some Linux distros, such as CachyOS.
Not always needed. All it does is replace setupKeyboardCallbacks in com.mojang.blaze3d.platform.InputConstants with a version that try/catches each line, ignoring NullPointerException.
