"This Twitch account is already linked to another Epic Games account" error

If you are receiving this error, you could have previously had a secondary Epic Games account linked to your Twitch account. As a workaround, follow these steps:

1. Log into the secondary Epic Games account. If you are unable to access the account, follow guidance in How can I recover access to my Epic Games account?

2. In Settings of this Epic Games account, link to your Twitch account. See How do I link my Twitch profile to my Epic Games account?

3. If the linking is successful, unlink the accounts immediately.

4. Log into your primary Epic Games account that you wish to connect to your Twitch account. The "hidden" connection with the secondary account causing the error should now be removed.
