I mean idek how you are toggling fly that fast, but Mojangs flying netcode is very broken, and Grim mostly disables itself with flying because of clients like Lunar having built-in cheats

This is the same as #1286 / #973

See https://github.com/GrimAnticheat/Grim/issues/973#issuecomment-2075194909

idk if this is relevant, but in this commit https://github.com/GrimAnticheat/Grim/commit/4b86d5827cd4d79886eda1f4fdd7066d132b271b some piece of code that seems to be important to determinate in which tick flying should be applied to was removed
