Werewolves Transformations for 2021.1?

Basically, Im trying to make a way that my Lycanthrope Villager can turn into a Werewolf at night, and Vice Versa for the Werewolf, However all the topics on this were from multiple years ago, (last topic looked to be from 2019) and therefore the coding is outdated. i tried to fiddle with it a bit and modify the coding, and it kind of worked. the werewolf would turn into a lycanthrope villager at day, but the villagre wouldnt turn at night, but the main problem here is that it would infinitely spawn the entities. if i spawned a lycanthrope villager it wouldnt turn at day, but neither would it turn at night, and the villager had basically lost all AI Movement capabilities because it was in an endless loop of despawning and respawning.
