Why do I get an error when I log in?

Hyper uses the Credential Manager to store your YouTube account. There must have been an issue while signing in and something went wrong!

You can try the following:

Remove your account by going to the Credential Manager in Windows (just search "Credential Manager" from the Start Menu). In the Credential Manager under Web Credentials you will see an entry for "HyperForYouTube" - click this credential and click remove at the bottom.
Now when you restart Hyper, it should allow you log in again. If you linked your account to a YouTube channel, it should now work.
