Failed to call hook...

This is a first time install of the plugin on the latest Rust version (Mar 4 2021). I'm getting the following error:
My config is attached.

InfoScreens.json

Awesome, that did the trick! I assume that it's trying to load the same thing twice. Once for the "default" group and once for the "admin" group, since I'm technically in both. Good catch.
And thanks for the quick response!
