When I executed !join, he got the following error:

Traceback (most recent call last):
  File "/usr/local/lib/python3.8/dist-packages/pyrogram/dispatcher.py", line 217, in handler_worker
    await handler.callback(self.client, *args)
  File "/root/tgvc-userbot/plugins/vc/player.py", line 297, in join_group_call
    group_call.client = client
AttributeError: can't set attribute

This is my logs:

it's a bug that it does not works with latest release of pytgcalls (v1.0.0), I just confirmed it. the current workaround is installing the previous version of pytgcalls

user@hostname ~ $ pip uninstall pytgcalls
user@hostname ~ $ pip install pytgcalls==0.0.23
