Error 0xFFFD0000 while running powershell script in task sequence

I am trying to run a powershell script during a Windows 10 inplace upgrade task sequence. The script exports Win 10 start menu tiles of the users and then imports them after upgrade.
I am getting error 0xFFFD0000 while exporting. The command lines I have used to run the script in TS are

powershell.exe -executionpolicy bypass -File  

and

Export_startmenulayout.ps1

But everything fails.

Could someone please help.
