if you /give a spawn egg (i used bat, although it most likely does not matter) that is set to spawn an area effect cloud, with the particle set to "item", and the item set to air, it kicks you from the world and wont let you back in, with the error "failed to encode packet 'clientbound/minecraft:set_entity_data'.

Here is the exact command i used:

/give @p bat_spawn_egg[entity_data={id:"minecraft:area_effect_cloud",Particle:"item air",Radius:1f,Duration:100,Motion:[0.0,1.0,0.0]}] 1
