Hi
Which version number of Office for Mac are you using now?
- I suggest you update Office to the latest one for a check.
Does this issue occur with other Office for Mac apps?
- I suggest you try to remove caches: Go to ~/Library/Containers/ Microsoft Excel
- If it does not work, please uninstall Office for Mac, then reinstall it from: https://learn.microsoft.com/en-us/officeupdates/update-history-office-for-mac#release-history-for-office-for-mac
Besides, you may start your Mac in Safe Mode, check if the issue also happens there? It helps us troubleshoot whether it is caused by third-party software installed.
