We’re aware of this issue and are working to fix it. As a workaround:
- Open UE and find the Fab plugin under the Window dropdown.
- Open the “Dark Ruins” listing (either from search or the Quixel profile)
- Click “Add to my library”
- Now open the Epic Games Launcher, click on Unreal Engine in the lefthand navigation, then Library in the top navigation, and refresh the Fab library.
- Dark Ruins should now appear in the Vault and you can use it to start your project.
