Simply deleting the files in the ‘C:\Users\AppData\Local\UnrealEngine’ folder should resolve the problem. It worked for me.

For the wanderers, this doesn’t work, it just hides the warning message. A quicker way to achieve the same is to simply right-click on the “eye” icon near the top-left of the “Outliner”, and uncheck “unsaved”.
