In rare occasions, Discord may freeze when your start Go Live or screen share on your Mac.
Disconnecting/reconnecting results in RTC_CONNECTING errors and you have to refresh (Cmd+R) the client.
The issue may occur after updating your Discord app.
We found the freeze happens when Discord attempts to initialize Rogue Amoeba's ACE library that is used for sound share.
Start by removing the Rogue Amoeba ACE Library. Once removed, then attempt to re-install the library once more.
