Does this occur with every new workbook, or with one particular workbook created recently?

There can be various reasons of-course, but mostly it will be:
When this occurs only for you, and with every new workbook, then your Excel itself is corrupted. Repair or reinstall your MS Office;
When this occurs after last update, and for others too, and with every new workbook, then last Excel update was faulty. Take the update back;
When this occurs only for you single workbook, then your workbook is corrupted. Create it anew, or open the faulty workbook, open a new one too, and use PasteSpecial to copy formulas, values, formats, etc. into new workbook. Save the new workbook, test it, and when all is OK, delete the old one (and rename the new one).
