Package Manager is not available on upgrading project

Packman

-

Project Manager option goes missing under the Window tab in Menu when a project is upgraded to next version. ( major release)

Steps to Reproduce:
1. Create a new project (say in 2018.2.f2)
2. Save project
3. Launch latest unity version (here, 2018.3.0a5)
4. Open the same project.

OR

1. Launch Unity3D 2018.3.0a5
2. Open Package Manager ( Window >> Package Manager)
3. Select Package Manager UI.
4. Downgrade version to 1.9.11

Actual Result: Package Manager is not available and errors are thrown in console.

Expected Result: Project should load without any errors and Package Manager should be available.

Work Around: Go to "Reset Packages to Default" under Help Tab in the menu, again add all the required packages.

Reproducible in : 2018.2.0a1 , 2018.3.0a5

Notes:
- Appears on both Mac and Windows
- As each major release has a different Package Manager UI version, it could be the possible reason that it breaks.

    @DANSTREAMAN's workaround worked for me in Unity2018.3.0f2, on version 2.0.3. Thanks!

    I cannot confirm if this is a long term solution, but navigate to your manifest.json file
    the error appears to be "package-manager-ui 2.1.1 does not exist"
    if you revert back to "package-manager-ui": "2.0.3"
    save, close
    re open file (will re load packages)
    then package manager will show back up, you may have to open the unity file a second time after it reloads the packages.
    Hopefully this gets fixed soon

    Anyone found solution yet? Or can it be fixed by downgrade?

    Same issue here with Unity 2018.3.4f1 on Windows 10.

    Workaround:
    - Close Unity.
    - Manually delete "Packages/manifest.json" in your project folder.
    - Restart Unity ("Project Manager" should be now visible in the "Windows" menu).
    - Add [again] required packages.

    And sorry to say that this bug is NOT yet fixed in 2018.3.4f1, so please re-open.

    Note I am seeing this after the supposed fix, on 2018.3.0f2

    I am experiencing this issue, but the work-around does not work. There appears to be no way to get the package manager UI to open, and compilation is failing due to missing packages.
