Sometimes we are not able to publish the workflow on Process Studio and when we do the Process Studio downloads and installs binary, it auto updates Process studio but doesn't reopen and gets a message as below:

And in logs we get as below : 

2021-07-26 21:46:06 main INFO  PSUpdaterMain:342 - Moving contents from Source [E:\Process-Studio\process-studio\tmp_updater\extracted\new_binaries\conf\fonts] to Destination [E:\Process-Studio\process-studio\conf\fonts]

2021-07-26 21:46:06 main ERROR PSUpdaterMain:84 - Error while updating Process Studio...aborting update!!

com.automationedge.ps.PSUpdaterException: Error while copying contents from source to destination directory

Go to tools then click on sync plugin & then try to publish workflow.
