I'm not sure that the install scripts work in Powershell's Constrained Language Mode.

I'm going to transfer this one to the install-scripts team to investigate the interaction here.

Hi @ip240Z,

I assume this issue is related to set policies on your workstation.

Could you check your $ExecutionContext.SessionState.LanguageMode in PS and share the result with us?

Feel free to reopen if it is still relevant for you.
