TypeError: issubclass() arg 1 must be a class

I have run this

from RealtimeTTS import TextToAudioStream, SystemEngine, AzureEngine, ElevenlabsEngine

engine = SystemEngine() # replace with your TTS engine
stream = TextToAudioStream(engine)
stream.feed("Hello world! How are you today?")
stream.play_async()

Error

Perhaps not elevenlabs==0.2.27? Currently this lib is not yet adapted to elevenlabs>=1.0.0

Solved!! Previously, I tried to install it using Python 3.8, and that's why I faced issues. Thx.
