Why TypeError: on_voice_state_update() takes 2 positional arguments but 3 were given Ignoring exception in on_voice_state_update?

Question

Python

When entering the voice, it gives an error like
TypeError: on_voice_state_update() takes 2 positional arguments but 3 were given
Ignoring exception in on_voice_state_update
I tried to solve the problem in different ways, but the result either does not start or this error

The code itself:
