Hello, I receive this error message every time I press 'Ctrl+C' in a live script.
Apr 11, 2018 6:18:12 PM com.mathworks.connector.message_service.impl.MessageServiceJSONImpl handlePublishRequest
WARNING: Error in subscription handler
java.lang.IllegalArgumentException: C:\Users\Abhishek\AppData\Local\Temp\ConnectorClipboard2848936797537281347 does not exist

What do I do? How do I fix this?

Hi there Abhi,
I've had the exact same problem. The Official MathWorks Answer: The potential cause for this issue is related to the Windows SilentCleanup Task. This issue is explained in detail at the following Microsoft Support page:
It may be temporarily resolved by restarting MATLAB. If not try out the following steps to test a possible workaround for this issue:
  • Start a command prompt as an administrator.
  • Please disable the SilentCleanup by executing the following command in the command prompt window:
schtasks.exe /change /TN \Microsoft\Windows\DiskCleanup\SilentCleanup/Disable
  • You can always enable it again later with:
schtasks.exe /change /TN \Microsoft\Windows\DiskCleanup\SilentCleanup/Enable
The Windows Build 1709 introduced some new functionality, which removes all empty folders in the TEMP directory. This could be the cause of the copy and paste error.

Is there a solution when there is no admin rights? Admin rights might be a problem for corporate Matlab users...

A possible workaround is using drag and drop, this still seems to work in the live editor.
Highlight the text in he live editor. Hold the Ctrl Key and Click and drag the highlighted text to where you want to paste it. Can be in same window or another window on the screen.

Cool. You can always drag and drop the text to Command Window and then you can copy it.

I tried the double drag and drop solution for a while, but it becomes very cumbersome when editing formulas etc. I did not want to disable Windows functionality because of a silly Matlab bug. So I found another solution:
Try to copy something, then in the error message read which folder is missing. Make a new folder in Temp with that name, and put a dummy file in it, so that it does not get deleted. Now copying works for the current Matlab session. It even worked after a restart of Matlab with the same script, at least for the time being.
Files in Temp tend to be temporary, so this procedure probably has to be repeated now and then, maybe after reboot or after changing active working directory or something. But it is better than not having copy/paste. And frankly better than spending hours upgrading Matlab too (if there is even a fix in the newest version)...

Simply drag with your mouse

I'm also experiencing the same issue with exactly the same error message.
And it's related to a folder in Temp, so SilentCleanup Task's involvement makes sense!
>schtasks.exe /change /TN "\Microsoft\Windows\DiskCleanup\SilentCleanup" /Disable
ended up with an error:
'schtasks.exe' is not recognized as an internal or external command,
operable program or batch file.

you can try this command in power shell, first of all open windows power shell ise, then copy-paste the command text to the editor, the use the run button...
and also to work this command, or disable the task of DiskCleanup\SilentCleanup another way could be followed. in windows, please open task scheduler tool, then at the left side, use the tree list, go to the item of library/microsoft/windows/DiskCleanup/SilentCleanup. the at the task of SilentCleanup, at the right side, you can use disable the task link...
i have done succesfully to diable the task, but i don't know it could be worked for my cronic copy-paste matlab editor problem... because after windows restarting, i'll check the problem...
my matlab version is 2021b, and the copy-paste action in editor works, but in the MATLAB command window, the copy-paste action doesn't work. many solutions in the forums should recommend drag the copied text to the area, ok this works and the best solution is this, but with powerfull tool MATLAB, not working with copy-paste action has been occurred many times, when i have investigated the issue, from past to now, many times with many MATLAB versions, this problem occurs, when you see the sorum pages, this problem has been occured in MATLAB version of 2009, 2018, 2021, 2022...
honorable important stuff at mathworks, please solve this issue, or add a wizard to solve the prolem how can we could try and apply steps in the main MATLAB window, please do this, not using copy-paste action is very disgusting situation...
thanks to be interested in the issue, and the support us MATLAB users from past to now... from 2009 to 2022, please solve this situation now...
