As the title said.
details: hitboxes are at abnormal size...(All description here, is under MC 1.16.5 environment.)

use "/summon" command or use spawn egg. They'll suffocate in blocks below them or stuck in a transparent block, or floating in mid-air.

voxelShape or hitbox size should be fixed. And the position also.
