Please back your project up before you do this

Looks like it could be coming from nDisplay. If that was one that got disabled, you might be able to go into your uproject file and change these lines:

			"Name": "nDisplay",
			"Enabled": true,
			"SupportedTargetPlatforms": [
				"Win64",
				"Linux"
			]
		}

Try adding it if it’s not there, or removing it if it is.
