Hey, thanks for reporting.

This seems very similar if not the same issue as Ongoing Bug within UEFN aka Epic Games Inc. outdated or missing authorization repository (lore).

I’d recommend trying this first:

• Log out of UEFN and close it
• Log out of the Epic Games Launcher and close it
• Relaunch/log into the Epic Games launcher
• Relaunch UEFN
• Confirm whether the problem returns/persists
