Since installing Catalina 10.15 and Office 365 16.30 (updates installed the same day (something I will not due again)) when I attempt to save a workbook that I have used for a couple of years, I receive the alert: 'Your changes could not be saved  to xxx.xlsx due to a sharing violation.  I then receive the alert The file format end extension of 646820000.mactf don't match. 

I contacted the Answer Desk who say it is an Apple Product and Apple support said it is a Microsoft problem.

Any thoughts or suggestions will be appreciated.

    The latest insider fast build for 16.38 that was just released resolved the issue for me.
