Hi everyone,
This is an issue that we have been trying to track down. If you could post your ‘Verbose Logs’ and a screenshot of your Manifest folder it would be much appreciated.

Manifest folder location:
C:\ProgramData\Epic\EpicGamesLauncher\Data\Manifests
After you post your logs and screenshot, if you would like to continue helping us troubleshoot this error please wait for us to reply. If you need to be up and running asap, the only workaround we currently have for this issue is to uninstall and re-install the Launcher.
