Textures of animals are broken

Hello! After adding a Naturalist Add-On to the Realms world, animals textures appeared to be broken. But deleting add-on didn't help. I even restored 2h version, when noone seemed any issues — but it still broken. I can't find the reason and everyone upset. It's the same for the Realms and for the copy on device. Can you help, please? What do I need to change to find the issue?
