    Hello @Mills Leonora

    As you described, when you open the Excel app you see this message:

    "I'm sorry, but Excel encountered an error that prevented it from working properly, so you need to close Excel. Do you want us to fix it right away?"

    Could you confirm whether it also mentioned more details about the error code or message? That information would help in addressing the issue more effectively.

    Also, did it ask you to repair Excel immediately, or only to close it?

    • If it only asked you to close, try quitting Excel completely, restarting your computer, and then opening Excel again to see if the problem reappears.
    • If it asked you to repair now, you can try the repair option, wait for it to finish, and then reopen Excel to check if it works normally.

    In addition, you can try these steps to continue working with Excel:

    1/ Use the Excel web browser version temporarily.

    2/ Open Excel in safe mode to see if the issue persists.

    • Press Windows + R
    • Type: winword /safe (for Word) or excel /safe (for Excel)

    If it works in Safe Mode, add‑ins may be causing the issue

    3/ Repair Office apps 

    • Save your work and close all Office programs
    • Press the *"Windows Key + I" *to open "Settings. 
    • Go to "Apps"> "Installed apps". 
    • Type Microsoft 365 or Office in the search bar. 
    • Click the "three dots (...)" next to the name and select "Modify". 
    • In the window that appears, select Online Repair. 
    • Click "Repair", then click Repair again to confirm.

    Try these steps in order on Windows:

    1. Update Office
      • Open any Office app.
      • Go to File > Account.
      • Under Product Information, select Update Options > Update Now.
    2. Start Excel in Safe Mode
      • Press Windows + R.
      • Type excel /safe and press Enter.
      • If Excel opens in Safe Mode, the issue is likely caused by an add-in.
    3. Disable add-ins if Safe Mode works
      • In Excel, go to File > Options > Add-Ins.
      • In the Manage list, select Excel Add-ins or COM Add-ins, then select Go.
      • Clear one add-in at a time, select OK, and restart Excel normally.
      • If Excel starts after disabling one add-in, that add-in is the cause.
    4. Repair Office
      • Close all Office apps.
      • Open Settings > Apps > Installed apps.
      • Find Microsoft 365 or Office.
      • Select the three dots > Modify.
      • Run Online Repair.
      • Restart the PC after the repair finishes.
    5. If Safe Mode does not work
      • The issue is not likely caused by add-ins.
      • Use Repair Office or uninstall and reinstall Office.

    A common cause of this error is a corrupted Office installation or a problematic add-in.
