• The Window->Package Manager menu item disappears in Unity 2018.3, 2018.4, 2019.1 if you upgrade a project with compilations errors. This will be fixed in an upcoming 2019.1 patch release. Workaround: You can try to close Unity and reopen your project. Sometimes, the Package Manager window will reappear.
