Matlab live script codes are not allowed COPY and Paste

it's so weird that cannot copy code from livescript, do you have this question. My matlab release is 2017b.

The issue is still the case in 2021b. Even worse - copy/paste does not work in ordinary scripts. I've copied a piece and the only place I could paste it - Command Window. Any solutions?

The issue may be temporarily resolved by restarting MATLAB.

Additionally, we believe that a potential cause for this issue is related to the Windows SilentCleanup Task. This issue is explained in detail at the following Microsoft Support page:

https://support.microsoft.com/en-us/help/4015218/activex-is-automatically-deleted-in-the-windows-10-x86-environment

You may try out the following steps to test a possible workaround for this issue:

1. Start a command prompt as an administrator.

2. Please disable the SilentCleanup by executing the following command in the command prompt window:

schtasks.exe /change /TN “\Microsoft\Windows\DiskCleanup\SilentCleanup” /Disable

3. 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.

The bug will be fixed in a future release of MATLAB.
