I was able to get mine to work. I actually had to uninstall Opera redownload it and reinstall it fresh. Once I did that it works just fine.
Idk what’s wrong with it but if it happens again I don’t think I’ll keep using it. I really love using it but that’s way too much of a hassle to have to do once a month.

I cannot log into twitch. I can open the Twitch.tv website, but when i try to log in i get an error that says i am not using a supported search engine. I was able to use opera two days ago, but the update happened on my computer today and now i can no longer log into twitch.
The only reason i use Opera is for the Widgets on the sidebar, if I can't use twitch I will not be using Opera.

@xace1k I am having the same issue. This deleting of cookies thing did not work for me. Opera did an update now i can't use Twitch- well I can't login. i can watch without logging in but thats all.
