    Try these fixes in this order:

    1. Repair Office first
      • On Windows 10/11: Start > Settings > Apps > find Microsoft Office / Microsoft 365 > Modify.
      • Choose Online Repair and complete the repair.
      • If only file opening is broken when double-clicking, a Quick Repair can also help.
    2. Check whether Excel is opening a blank screen
      • Open Excel.
      • Go to View > Unhide. If a workbook is listed, select it and choose OK.
      • Try minimizing Excel, then restore/maximize it again. This can refresh a hidden workbook window.
    3. Reset the Excel file association
      • Right-click an .xlsx file > Properties.
      • Next to Opens with, select Change.
      • Choose Excel, check Always use this app, then select OK.
      • If needed, use Control Panel > Programs > Default Programs to set Excel as the default for Excel file types.
    4. Disable Excel add-ins one by one
      • In Excel, go to File > Options > Add-Ins.
      • At the bottom, in Manage, select COM Add-Ins > Go.
      • Clear one add-in, select OK, then restart Excel and test opening the file.
      • If the issue continues, repeat for the other COM add-ins.
      • Then repeat the same process with Excel Add-Ins.
      • If Excel starts opening files after one add-in is disabled, that add-in is the cause.
    5. If Excel asks to “Grant Access” and then hangs
      • Update Excel to version 16.34 or later. That specific issue was fixed in version 16.34.
    6. Temporary workaround
      • Open Excel first.
      • Then use File > Open and browse to the workbook.
    7. If repair does not fix it
      • Use the Contact us option in Microsoft Support for additional troubleshooting.

    Important: If a step involves registry changes, back up the registry first. Incorrect registry changes can cause serious problems.

    Hi Ajay, 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.
