Regression
Yes
Errors appear when upgrading the project from 2018.2 to 2018.3
Steps to reproduce:
1. Open supplied project with Unity 2018.2.0b8
2. Open supplied project with Unity 2018.3.0a1
Expected: no errors appear on the latter version because there were none on the former version
Actual: errors appear (see "Errors") which make the scene unplayable
Reproduced in: 2018.3.0a1

Try deleting Library folder in the root and let the new Unity version create it again.

Find cached version of com.unity.package-manager-ui (Version that worked for me was 2.0.3) and change it with your current project version. If you use Windows version of Unity you can find caches in AppData
