    Hi Bendeguz Fazekas,

    Since the Office repair and startup troubleshooting have already been covered, the next step is to determine whether the issue is tied to Excel’s user configuration.

    1, Reset Excel’s startup configuration

    • Close Excel.
    • Press Windows + R, type %appdata%\Microsoft\Excel and press Enter.
    • If an XLSTART folder exists, temporarily move its contents to another folder.
    • Reopen Excel and test.

    Files or templates loaded automatically from XLSTART can sometimes prevent Excel from starting normally.

    2, Test with a new Windows user account

    • Create a temporary local Windows account and open Excel there.
    • If Excel works normally in the new account, this points to an issue within the original Windows/Office user profile rather than the Office installation itself.

    3, Check Reliability Monitor

    • Press Windows + R, enter perfmon /rel, and look for the Excel failure.
    • If an error is listed, please share the Faulting application, Faulting module, and Exception code. Those details can help narrow down what is causing Excel to stop.

    I hope one of these checks helps isolate the cause. If the issue continues, please share the Reliability Monitor details and we can narrow down the next step.

    That built-in Repair Now prompt may not complete the full Office repair. The supported next step is to run an Online Repair for Office manually.

    1. Close Excel and all other Office apps.
    2. In Windows, right-click Start and open:
      • Installed apps on Windows 11, or
      • Apps and Features on Windows 10.
    3. Find Microsoft 365 or Microsoft Office in the list.
    4. Select it, then choose Modify.
    5. In the repair window, select Online Repair > Repair.
      • Online Repair is the more complete option.
      • Quick Repair is faster, but it only detects and replaces corrupted files.
    6. Follow the on-screen steps and let the repair finish.
    7. Restart the PC.
    8. Open Excel again and test the file.

    If Excel still opens to a blank screen after the repair, the recommended action remains an Online Repair.

    If Excel opens but a specific workbook fails, try recovering that file with Open and Repair:

    1. Open Excel.
    2. Select File > Open > Browse.
    3. Select the workbook.
    4. Select the arrow next to Open.
    5. Choose Open and Repair.

    If Excel hangs or freezes during startup, test it in safe mode by running excel /safe. If it opens there, an add-in may be causing the problem.

    Also make sure Office is fully updated. A known Excel file-access hang issue was fixed in version 16.34 and later.
