Armor Mod issue when put on followers.

[WindsSovereign]

So, I've downloaded an armor mod from bethesda's site. Then downloaded it within the mods game menu. It made it crash, so I figured I'm gonna copy the bsa and esp files from my data folder, then pack them into a zip, and add to nexus mods manager. The issue is, armor works when I use it on myself, but it doesn't work when I give it to my follower. As soon as I give my follower a single piece of this outfit, he disappears. No matter which piece. I really need help on this one from someone that knows what he's doing. This is the armor: https://bethesda.net/en/mods/skyrim/mod-detail/3244439
