    seq, request = rpc.request_queue.get(block=True, timeout=0.05)

During handling of the above exception, another exception occurred:

    return self.func(*args)

    daniel.deselect()
AttributeError: 'Radiobutton' object has no attribute 'deselect'

Variable daniel will have to an instance of class Radiobutton.

check with
print(type(daniel))

You can also just select another radio button. It will deselect the others.
