I don’t know if this will help or not, but I just ran into a similar issue with Epic’s page infinitely redirecting, and was able to stop that by removing my browser’s stored site data for unrealengine.com and epicgames.com.
This was for Firefox, and was done by opening Settings, Privacy & Security, Cookies and Site Data, Manage Data, finding and selecting unrealengine.com and epicgames.com and removing the data for those.
