Hey
Since the editor did not launch when you went to the direct path, I would highly suggest that you uninstall the editor at this time and reinstall it. You can easily do that by going to the Epic Games Launcher and clicking on the drop-down arrow, there is a ‘remove’ button listed there which will uninstall that version of the editor.
Once it’s reinstalled, please let me know if you’re still running into this error. Thanks!
