I updated the addon DBM. I did have the 8.2 release version. Automatic update went to 1.13 version for Classic wow. I had a warning pop up in my chat telling me to uninstall and find the correct version.

this was probably caused by having clent already running when the update to support classic rolled out (twitch client update)

I would hope restarting twitch client should fix this, if not though, there is literally nothing I can do about it and you'll have to report issue to curseforge.
