Oh, I think I have found the way to resolve the issue. You can try to delete the `CitySampleCookedEditor.Target.cs` file. It’s worked for me.

Refer to: [The CitySample project is not generated .sln - #4 by WATY22461](https://forums.unrealengine.com/t/the-citysample-project-is-not-generated-sln/1343145/4)
