You never set the value of text_input, so it is still the default None. Just setting an id doesn't set that attribute. There are a couple easy fixes here.

First, you can fill in that value:

<OptionMenu>:
    # this sets the `text_input` attribute to the value
    # of the `text_input` id below
    text_input: text_input
    ...
    TextInput:
        id: text_input
    ...

Alternatively, you can access the widget via the ids collection, and remove the text_input attribute completely:

def load(self, path, filename):
    with open(os.path.join(path, filename[0])) as stream:
        # self.ids is the collection of ids for this widget rule
        self.ids.text_input.text = stream.read()
    self.dismiss_popup()
