You can't immediately cause this error with limboapi separately, but if you install another plugin (LimboAuth) using this api, the error will manifest itself

guesses why this is happening: LimboAPI sends the registry with an empty zombie_nautilus_variant, which the 1.21.11 client rejects

version velocity: latest
LimboApi: latest build
