Can't open SSMS 18.1 - "MRU Package did not load correctly" and "Cannot create the window" RRS feed

  • Question

  • I'm sorry if this is not the right forum category, I couldn't find "SQL Server Tools" from the list.

    This issue is driving me crazy. I can't open SSMS 18.1. When I try to open it I get the follow things:

    • Starts fine with the small window that says "Microsoft SQL Server Management Studio v18.6"...
    • But then I get an error window saying:
      "The 'MRU Package' package did not load correctly.
      The problem may have been caused by a configuration change or by the installation of another extension"...
    • After that I get another error window saying:
      "Cannot create the window".

    Here's an Imgur link with pictures of the errors (can't post a link): imgur.com/a/xxz0OOn

    And that's it. I can't open SSMS.

    Things I've already did/tried:

    1. Installed SSMS 18.1
    2. Installed SQL Server 2019
    3. Uninstalled Visual Studio 2017
    4. Installed Visual Studio 2019
    5. Re-installed SQL Server 2019
    6. Repair installation of SSMS 18.1
    7. Re-installed SSMS 18.1
    8. Installed Visual Shell 2015
    9. Rebooted PC several times

    I don't know what else to do. I've been struggling with this since yesterday. I've searched for solutions but couldn't find anything.

    Hope someone can help me. Thanks in advance.

  • If nothing works and you have time, then maybe try this method:

    • Uninstall all products, all versions: SSMS, SQL Server, Visual Studio, Data Tools and other components that are related to SQL and Visual Studio, or which are not needed. Use Control Panel, Uninstall to view the products.
    • Restart the computer, go to Settings and apply all of updates, if any.
    • Restart the computer and install the latest SSMS, which is 18.6.
    • Check if SSMS works. Try accessing some external database, if any.
    • Install SQL Server 2019, check if you can access it from SSMS.
    • Install Visual Studio, etc.
