Написал код
@client.event
async def on_voice_state_update(member,before,after):
if after.channel.id == 789090452162609212:
for guild in Bot.guilds:
maincategory = discord.utils.get(guild.categories, id=789090413033291787)
channel2 = await guild.create_voice_channel(name=f'Приватка {member.display_name}',category = maincategory)
await channel2.set_permissions(member,connect=True,mute_members=True,move_members=True,manage_channels=True)
await member.move_to(channel2)
def check(x,y,z):
return len(channel2.members) == 0
await Bot.wait_for('voice_state_update',check=check)

В итоге при заходе в войс ничего не происходит а в консоли пишет
