Imported rig completely breaks in blender

I’m using the Blender animation rig exported plugin thingy by Den_S and the rig’s “textures” got broken the first time I’ve imported it


Then I’ve noticed that there’s a “Dummy72” object or whatever in the top right tab
(this is my second time using blender)

And when I tried to move it to check what it was it just moved the rig’s face

I’m currently at a roadblock because I have no idea on how to fix this and why this is happening since last time I’ve tried animating (a really long time ago) everything was working well

EDIT: I just noticed this warning in the plugin’s rig loading warnings
