Overview of the Issue

I am working on an automation pipeline that will utilize packer to create custom compute images in Oracle Cloud Infrastructure. The packer build uses a variety of powershell provisioner blocks to provision the custom image. For some reason, at seemingly random points while packer is provisioning the image, packer will return an error similar to the one below:

==> oracle-oci.server2019: & : The term 'c:/Windows/Temp/packer-cleanup-64f1b11f-a3a0-8cd0-650a-5c290ac64efd.ps1' is not recognized as the name

The above example that I provided appears to be associated with the cleanup script that packer uploads to and and runs on the packer image to cleanup the powershell scripts that provisioned the image, but I am also seeing a similar error occur for other scripts as well, like the one below:

Windows PowerShell
    oracle-oci.server2019: Copyright (C) Microsoft Corporation. All rights reserved.
==> oracle-oci.server2019: The argument 'C:/Windows/Temp/packer-elevated-shell-64e01ace-0e63-ff7f-5e24-a97293581a92.ps1' to the -File parameter does not exist. Provide the path to an existing '.ps1' file as an argument to the -File parameter.
    oracle-oci.server2019:
==> oracle-oci.server2019: Provisioning step had errors: Running the cleanup provisioner, if present...
==> oracle-oci.server2019: Terminating instance (ocid1.instance.oc1.iad.anuwcljsf256y7icqgcjn5wsjgxtbn5uql2cwzyhonomlikwhmjiggauvqqa)...
==> oracle-oci.server2019: Terminated instance.

I am not sure what is going on, but there appears to be some kind of issue with the powershell provisioner.
