We could not copy the content to the Clipboard, it is in use by another application. You can still paste your content within this workbook but it will not be available in other applications.

Due to features change often I often run a file that I copied from a helpful note.

I created a batch file and run it in administrator mode. It replaces corrupt or broken files.

I have had no problems with this code.

However, provide for recovery, if needed. This is "as is".

Perhaps try one command at a time.

aja.bat

@echo off
date /t & time /t
echo Dism /Online /Cleanup-Image /StartComponentCleanup
Dism /Online /Cleanup-Image /StartComponentCleanup
echo ...
date /t & time /t
echo Dism /Online /Cleanup-Image /RestoreHealth
Dism /Online /Cleanup-Image /RestoreHealth
echo ...
date /t & time /t
echo SFC /scannow
SFC /scannow
date /t & time /t
pause

From what I can tell the excel clipboard function does not mitigate well with the Windows OS clipboard and CPU. Good luck on trying a dependable, online workaround for Office 365 Excel (it seems every MS coding and/or feature "improvement" is an overall digital ecosystem detriment ... I guess it keeps their programmers employed).

WORKAROUND: I sometimes have to open the Task Manager to determine what apps are using a lot of the CPU and close that. In conjuction with that I often try to clear the the Excel Clipboard function located on the left of the ribbon and expanding it with the lower right down arrow then clicking the Clear All button to remove all the copy/paste conditions that are listed.

It may help to automate the Windows Clipboard cmd with the Clear Clipboard command icon. See: How To Create Clear Clipboard Shortcut In Windows 10 - YouTube

Also clear your RAM which can be done conveniently with the freeware/shareware Advance SystemCare RAM monitor/clearing function. While in the Task Manager, you can also remove unecessary apps from the Windows startup by going to Task Manager-> Startup list. Sometimes these lingering unecessary apps may interfere with efficient memory activity.

Not that these solves the problem --- it is just that --- a possible workaround.

Thank you KA, this solution worked for me! I was struggling from past 2 days so much appreciated

The problem, for the most part, has stopped. Not sure what could have fixed it. I do ocassionally get a different warning where it suggest I have a copy function selected already and pending. It then prevents me from selecting cells. I have found that saving the Excel document and restarting reset its normal function.

As for enabling Live Preview, here is a link with the procedure:

Sure, that's working for me, under my architecture.
