Hello James,
I’m Florentino one of the Independent Advisor and I’d be happy to help you out with your question.
If this concern is also occurring in other Excel files, we can say the problem is with the application itself. Therefore, we suggest that you perform all primary troubleshooting steps to resolve this concern. Please follow each method below and get back to us with the results:
Method 1: Install Office Update.
Open Excel.
Click on File.
Go to Account.
Under Product Information, choose Update Options and click Update Now.
Once the updates completely installed, relaunch Excel and see if the problem occurs.
Method 2: Open Excel in safe mode.
Press the Windows and R key on your keyboard simultaneously.
In the Run command, type excel /safe (include space between excel and / symbol) and then click OK.
Once the Excel app opens in safe mode, observe the issue if it is persisting.
If the issue doesn’t occur while in Safe Mode, then an add-in is likely causing it. To disable add-ins, please access this link and follow the steps under Permanently disable or remove an add-in.
Note: To stop Office Safe Mode, just exit and restart your Excel application.
Method 3: Repair Office program.
Right-click the Start button (lower-left corner).
Select Apps and Features.
Right-click the Microsoft Office program and select Change and then choose Online Repair.
Click Repair and follow the on-screen instruction to continue. Restart your computer and check if the concern is still occurring.
