I have removed and reinstall the add-on 4 times from Twitch but still get the error. Not sure what else to try. This if for version 2.06.

Are you trying to install the BFA version of the addon? The Twitch app sometimes gets confused and will install the Classic version when you want the BFA version or. The opposite can happen as well where the Twitch app will install the BFA version when you want the Classic version. You can manually select which version of the addon you want by going to the Versions tab in the Twitch app.

Thank you but when reading you post it hit me to go check the add-on folder after I removed it a few more times and I found it was deleting the add-on but leaving behind the folder for Classic. Deleted the folder, installed and the issue is gone. Thank you for the help.
