To set the System Master Page in SharePoint 2019 using PowerShell, you can follow these steps:

1. Open SharePoint Management Shell as Administrator

2. Run the below PowerShell Script with your site URL

    $SPWeb = Get-SPWeb "http://debug.to/sites/HR/"   #P.S: SiteURL
    #Set the current site master page to the default master page
    $SPWeb.CustomMasterURL = "/sites/HR/_catalogs/masterpage/oslo.master" 
    $SPWeb.Update()
