Microsoft 365 Excel (or Word) “has run into an error that is preventing it from working correctly. Excel (or Word) will need to be closed as a result. Would you like us to repair now?”
I answered “Repair Now”. I can still use Excel (or Word) for a minute or two, then it closes.
Reopening Excel (or Word) doesn’t fix it. Rebooting the computer doesn’t fix it. Worked fine this morning (8/9/2023) but not this afternoon.
I was thinking of reinstalling but I should probably find & copy the install key first but not sure where that is. Any other thoughts?
