Hey Amber I appreciate your detailed solutions to this issue! I am also having the same issue with the plugin both not showing in Blender and also not showing up after trying to manually install it in Blender. This happens with plugins sometimes that become outdated after Blender moves to a new stable version, as it just did to 3.2. I wonder if this might be a incompatibility that needs to be addressed. Either way I'm going to poke at it more.
Thanks again!
