Besides, please ensure your Microsoft 365 apps are fully updated, sometime updating Office fixes issue.

The latest version of Current channel is 2101 (Build 13628.20448). For other channel version info, see Update history for Microsoft 365 Apps (listed by date)
If the version is not updated as mentioned in the article, please install updates and check if the issue remains. To know how to install updates, see Install Office updates.
if the issue remains, please repair Office apps from Control Panel instead.
