Hi @DM_PSX,
Could you try visiting http://metahuman.unrealengine.com/logout to logout of the MetaHuman Launcher and log out of unrealengine.com? Then, make sure you’re manually logging into unrealengine.com and metahuman.unrealengine.com with the same account—no saved or stored credentials.
Hopefully this should get you through. Our team has been able to reproduce the looping issue, so we’ll dig into that. It does look like your account has the appropriate settings to be able to access MetaHuman though!
