Can't find this anywhere

I can not get WoW Classic to launch through twitch to use my addons, no matter what. I’ve uninstalled, relocated the game and everything. Where I currently am, WoW is downloaded, Twitch has located the game, but my play button is highlighted and it doesnt click, like no loading happens its just doesn’t go, however its not grey’d out its highlighted like the game should be launching, repairing the files isnt working either. I dont have current wow installed only classic. idk where else to post. or if theres another addon manager I can use.
