A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hi, good day!
This is a known issue with the KB5002914 update, and Microsoft is already aware that some Excel users are experiencing problems with copy/paste and related cell operations.
Since these functions are critical to your daily work, I understand the frustration. For now, I recommend keeping Office updated and checking for the next Office update, which should be installed once Microsoft releases the fix.
Unfortunately, Microsoft Q&A cannot send individual notifications when the fix becomes available. However, you can monitor Microsoft's Office update information and then verify that copy/paste and formula-fill are working normally after the corrected update is installed.
