Short description of error
Blender crashes when attempting to create a new group input for geometry nodes as shown in the script.

Exact steps for others to reproduce the error

Add a geometry node modifier and node group (e.g. press New in the Geometry Node Editor)
Run the script below

import bpy
nodes = bpy.data.node_groups
node = nodes["Geometry Nodes"]
group = node.nodes["Group Output"]
group.inputs.new(name="Output",type="Color")

Obviously we should avoid the crash here, but this is not high priority to me because this is not how new inputs/outputs to a node group should be added. Instead group inputs/outputs should be added directly on the node tree (node_tree.inputs.new). The corresponding sockets on the nodes should be created automatically.

Has anyone been successful in creating the input socket by calling node_group.inputs.new?
I tried executing the following from console:

C.object.modifiers[0].node_group.inputs.new('VALUE', 'test')

This gives:

RuntimeError: Error: Unable to create socket

found this by bumper car. the syntax changed.

NodeSocketInterfaceFloat is now NodeSocketFloat

bpy.context.selected_objects- [x].data.materials- [x].node_tree.nodes['Group'].inputs.new(type="NodeSocketFloat", name="muffin")

works.
