Lack of permissions to access a resource used by script (Registry, File system, Service, etc...).
Resource (Registry, File system, Service, etc...) is slow, offline, or in a corrupted state.
The computer does not have enough resources (for example; memory) to run the executable.

After reviewing the error in the context, check:

That the PowerShell script executes on the computer without error.

That the PowerShell script is configured correctly Data Item references are valid and present.

That the Action Account has access to the resources used by the PowerShell script.

That the computer is not over utilized.

Save the PowerShell script to a file and run it through PowerShell.exe.
Check Task Manager to see if there is enough free memory.
Check Task Manager to see if there are any processes consuming all the CPU.

Another error can be caused by the misconfiguration of the workflow executing this script. The configuration Snap Ins, Parameters, or Timeout Seconds could be incorrect.
