Can't create dummy using the Rig Builder plugin

Hey!

I’m not really sure if this is the right place to ask, but when trying to insert a R15 Block Rig Dummy using the Rig Builder plugin, I get this error:

builtin_RigBuilder.rbxm.RigBuilder.RigCreator:255: attempt to index nil with 'Parent' 

Is there any way to fix this?

Try to reinstall plugin, if that doesn’t help let me know

I can’t uninstall it, it’s a built-in plugin in Studio
