Hi
We have noticed this issue across multiple customers using Office 365. Excel fails to open and in task manager the exe is listed as a background process and is using CPU. Ending the process and opening in safe mode do not work. So far the only fix has been to run an online repair however we have had a couple of computers where this issue has returned. The customers are running version 16.0.13426.20308 which was rolled out on December 2nd. I could not find anything listing issues with the most recent build. Any help would be appreciated.

No error messages, Excel just does not open. excel.exe opens as a background process in task manager.
Is this an issue with the most recent Office update?
Hi Luke,
We understand the inconvenience caused and apologize for it. And we will try our best to help you.
Regarding to “Is this an issue with the most recent Office update?” as far as I know there is no member reporting same issue (Excel fails to open) in Office 365 latest update in this community and I also tested from different channel and it seem work fine form our side.
Since you mentioned issue happen to multiple user’s machine it maybe causes due to your organization environment. If possible, please try to let users uninstall Office 365 completely by using Microsoft Support and Recovery Assistant (SaRA) as uninstalling Office through Control Panel > Programs & Features would keep some preferences for next installation. Then re-install Office.
I appreciate your patience and understanding.
Best Regards
Waqas Muhammad
