Additional Context

Bot worked without issues for years, until today. I already tried a clean install, and resetting the bot token.
Seems like others are having a similar issue: https://stackoverflow.com/questions/79664160/discord-py-bot-keeps-reconnected-and-disconnecting-from-voice-channels

Thank you. In the meantime, is there a fork/branch/workaround I can use?

Can confirm, having this same issue on my TTS bot. Fix would be very helpful as this is an accessibility tool.

Really glad I'm not the only one having this problem. I run a bot called "CheersBot V2" and it seems to be having trouble on manual and automatic join (to Voice Channels).
