I would not recommend this solution. The issue with Citrix is that Unity (the engine Cities: Skylines runs on) thinks it's a graphics card. You may be able to run the game with this option, but it's running of the virtual GPU Citrix creates, NOT your actually GPU.

If you're on Windows 10 the easiest way is to uninstall Citrix and then install the version from the Windows 10 App Store. It lacks the feature that causes problems with Unity games.

Alternatively, you can reinstall Citrix from the Command Prompt using the following command:

CitrixWorkspaceApp.exe ADDLOCAL=ReceiverInside,ICA_Client,AM,SELFSERVICE,DesktopViewer,Flash,Vd3d,WebHelper,BrowserEngine
(there's a space after the executable name like a typical parameter)

This will install Citrix Workspace without Workspace Hub which has the Citrix Casting driver causing the crashing.
