Twitch client installed classic/retail version on retail/classic

Describe the bug

Do you have an error log of what happened?

To Reproduce

Screenshots

Did you try having DeadlyBossMods as the only enabled addon and everything else (especially something like ElvUI) disabled?

Which version of DeadlyBossMods are you using?

Was it working in a previous version? If yes, which was the last good one?

Additional context
