    Hi Ankit, 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.

    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.

    Start Excel in Safe Mode to determine whether an add-in is blocking startup; if Safe Mode also fails, run an Online Repair of Microsoft 365.

    1. Test Excel in Safe Mode

    1. Close the error dialog.
    2. Press Windows key + R.
    3. Enter the following command, including the space before /safe:
    excel /safe
    1. Select OK. The title bar should display Microsoft Excel (Safe Mode).

    Safe Mode bypasses Excel and COM add-ins, startup folders, and certain customized settings.^1^

    2. If Excel opens in Safe Mode

    An add-in is likely interfering with startup:

    1. In Excel, select File → Options → Add-ins.
    2. At the bottom, set Manage to COM Add-ins, then select Go.
    3. Clear all checkboxes and select OK.
    4. Close Excel and start it normally.
    5. If Excel now opens, re-enable add-ins one at a time, restarting Excel after each one. The add-in after which the error returns is the one to update, remove, or leave disabled.^2^

    If necessary, repeat this process with Manage → Excel Add-ins.

    3. If Excel does not open in Safe Mode

    Run an Online Repair, which repairs the entire Office installation:

    1. Close every Office application.
    2. Right-click Start → Installed apps.
    3. Find Microsoft 365 or Microsoft Office.
    4. Select the three dots → Modify.
    5. For a typical Click-to-Run installation, select Online Repair → Repair.
      • If the installer instead shows an MSI-based Change your installation window, select Repair → Continue.
    6. Complete the prompts, restart Windows, and test Excel again.

    Online Repair is more comprehensive than Quick Repair. Repairing Excel this way repairs the entire Office suite, not only Excel.^3^

    If the error remains

    • If other Office programs such as Word also show the same error, reinstalling Office is the next supported path after repair.
    • If only a particular workbook fails but blank Excel opens, the application itself is starting successfully; test a copy of that workbook rather than reinstalling immediately.
    • If Excel begins opening, install Office updates from File → Account → Update Options → Update Now.^2^
