    Try these steps in order:

    1. Start Excel in Safe Mode
      • Press Windows + R.
      • Type excel /safe and select OK.
      • If Excel opens, the problem is likely caused by an add-in or startup file.
    2. Disable COM add-ins
      • In Excel, go to File > Options > Add-ins.
      • Select COM Add-ins and click Go.
      • Clear all check boxes, then click OK.
      • Close Excel and open it normally.
      • If it works, re-enable add-ins one at a time to find the one causing the error.
    3. Check Excel startup folders
      • Excel can automatically open files from the XLStart folder or an alternate startup folder.
      • A bad file there can cause Excel to hang when opening.
      • Start Excel without those startup files and test again.
    4. Install the latest Office and Windows updates
      • Out-of-date files can cause Excel to freeze or stop responding.
      • Also check whether Excel is still busy with another process before clicking repair again.
    5. Repair Microsoft 365
      • Close all Office apps.
      • Open Settings > Apps > Installed apps.
      • Find Microsoft 365 or Office.
      • Select Modify.
      • Run Quick Repair first.
      • If the issue continues, run Online Repair.
      • Restart the PC after the repair finishes.
    6. Check antivirus software
      • Make sure antivirus definitions are up to date.
      • If the antivirus has Excel integration or an Excel add-in, it can cause performance or startup problems.
      • Changing antivirus settings can reduce protection, so use caution.
    7. Test the workbook locally
      • If the file is stored on a network location, SharePoint, web folder, or redirected folder, save a copy locally and open that copy.
      • This helps determine whether the issue is with the file or where it is stored.
    8. If Excel still hangs
      • Try a selective startup (clean boot) to check whether another background app or service is conflicting with Excel.
      • If the problem continues after all steps, contact Microsoft Support for guided troubleshooting.

    Important: If registry-based add-in troubleshooting is needed later, back up the registry first because incorrect changes can cause serious problems.

    Is this problem only occurring with one Excel file, or is the error occurring with all excel files?

    1

    If this problem is occurring with all Excel files.

    Before performing this process, 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, then scroll down to find Microsoft Office

    Select that and choose Modify - Online Repair

    That should fix any issues with your Office Installation.

    2

    If this problem is only occurring with one Excel file, log into your OneDrive in a web browser (https://onedrive.live.com/) to check if you have a working version of the file that you can download from OneDrive.
