To resolve this issue, you need to set execution policy to your machine-

Set-ExecutionPolicy -ExecutionPolicy AllSigned

You may also provide a scope to the current powershell session-

Set-ExecutionPolicy -ExecutionPolicy AllSigned -Scope Process

This should help resolve issue and any further powershell script execution process depending on what scope you provide the script to run.
