"This profile is already linked to another user" error when linking Ubisoft account to Epic Games account.

This error occurs when trying to link your Ubisoft account to an Epic Games account that is already linked to a different Ubisoft account.
To resolve this issue, unlink the Ubisoft account from your Epic Games account, and link the Ubisoft account you wish to use to access Ubisoft games on the Epic Games Launcher. Please note, if your Ubisoft account has previously been linked to an Epic Games account, you will only be able to link the same Epic Games account to your Ubisoft account.
If you would like to link a different Epic Games account to your Ubisoft account, contact Ubisoft Game Support.
