    Hi, this seems to be an ongoing bug with the Office apps for a couple of days which may be caused by an update, there are many people reporting this problem.

    1

    The 'Repair Now' button on that error popup dialog only performs a quick repair of the Office apps and that rarely resolves the problem with the Office apps, the best option is to perform a full online repair of your Office installation.

    Before performing this process to ensure you do not loose the Office installation during the repair, please log into your Microsoft account on this link (https://account.microsoft.com/services/) and check to ensure your Office licence or Microsoft 365 subscription is listed correctly on your account.

    Open the Settings App (gear icon on your Start Menu)

    Go to Apps - Installed Apps or Apps and Features

    Then, scroll down to find Microsoft Office or Microsoft 365.

    Select that and choose Modify - Online Repair

    That should fix any issues with your Office Installation.

    2

    If that does not resolve the problem, are you seeing any notification at the bottom right of your screen indicating Smart App Control security is blocking Office.

    Update Office first, then test the affected application in Safe Mode to determine whether an add-in is causing it to freeze or close.

    1. Recover your work and update Office

    If the application is still frozen, wait briefly before closing it because ending the process can lose unsaved changes. If it never responds, press Ctrl + Shift + Esc, select the frozen Office application in Task Manager, and choose End task.

    Then:

    1. Open any Office application that still works.
    2. Select File → Account.
    3. Under Product Information, select Update Options → Update Now.
    4. If Update Now is missing, select Enable Updates first.
    5. Let the update finish, restart Windows, and test the affected application.

    This update procedure applies to Office 2021, 2019, and 2016. ^1^

    2. Test the application in Safe Mode

    Safe Mode starts Office without most add-ins.

    1. Press Windows key + R.
    2. Enter the appropriate command, including the space before /safe:
      • Word: winword /safe
      • Excel: excel /safe
      • PowerPoint: powerpnt /safe
      • Publisher: mspub /safe
      • Visio: visio /safe
    3. Select OK and use the application for a few minutes.

    If it works in Safe Mode:

    1. Go to File → Options → Add-ins.
    2. At the bottom, select COM Add-ins from Manage, then select Go.
    3. Clear one add-in, select OK, and restart the application normally.
    4. Repeat until the application stops freezing. Leave the problematic add-in disabled or obtain an updated version from its publisher.

    If the application also freezes in Safe Mode, skip add-in testing and repair Office. Microsoft documents that this result indicates the problem is not caused by an add-in. ^1^

    3. Repair Office

    Repair affects the entire Office installation, even when only one application is failing.

    Windows 11

    1. Right-click Start → Installed apps.
    2. Find Microsoft Office 2021, 2019, or 2016.
    3. Select the three dots → Modify.
    4. Run Quick Repair first.
    5. If the problem remains, return to the same screen and run Online Repair.
    6. Restart the computer and test Office.

    Windows 10

    1. Right-click Start → Apps and Features.
    2. Select the installed Microsoft Office product.
    3. Select Modify.
    4. Run Quick Repair, followed by Online Repair if necessary.

    For an MSI-based Office installation, the displayed option is Repair → Continue rather than Online Repair. ^2^

    4. If it still freezes

    • Run Windows Update and install available updates. Microsoft also identifies outdated video, printer, mouse, and keyboard drivers as possible compatibility factors. ^1^
    • If only Outlook freezes, use Outlook-specific troubleshooting because its profiles and data files require different checks. The Outlook guidance applies to Outlook 2021, 2019, and 2016. ^3^
    • If updates, Safe Mode, and Online Repair all fail, uninstall and reinstall the matching Office 2021/2019/2016 edition. Keep the product key or the Microsoft account associated with that license available before uninstalling. The Microsoft uninstall troubleshooter requires Windows 10 or later. ^1^
