Dear Jennifer,
Good day and thank you for posting this in the forum.
As you mentioned in your post, the issue is happening with your Excel App in your home laptop/PC.
In such case, I would like to suggest some steps that you can check like:
- Try to clear the cache of the excel app.
Microsoft Office Upload Center - Microsoft Support
- Try to sync-up your OneDrive in your windows. Sync files with OneDrive in Windows - Microsoft Support
- Try closing your excel and try to restart your laptop too.
I would also like to ask if this particular excel file is only accessed by you or is it shared file with your colleagues?
Please note that my first response may not resolve your current situation immediately. But, with your help and more detailed information, we can work together to find a specific guidance for your current query.
Appreciate your cooperation and your valuable time.
