This can happen for a variety of reasons, such as a problem with the file itself or an issue with the Excel application.
Here are a few things you can try to troubleshoot the issue:
- Make sure you have the latest updates for Excel installed. You can do this by opening Excel and going to File -> Account -> Update Options and selecting Update Now.
- Try saving the workbook to a different location or with a different file name to see if that resolves the issue.
- If the workbook is linked to other documents, make sure that those documents are also saved and that the links are working correctly.
- Try repairing the Excel application. You can do this by going to Control Panel -> Programs -> Programs and Features, selecting Microsoft Office from the list of installed programs, and clicking Change. Then, select Quick Repair and follow the prompts to repair the application.
