This seems to be able to help. It does take down New Outlook and New Teams and any other Webview app first.
taskkill /f /im msedgewebview2.exe
$ResolveWingetPath = Resolve-Path "C:\Program Files\WindowsApps\Microsoft.DesktopAppInstaller_*_x64__8wekyb3d8bbwe"
if ($ResolveWingetPath){
$WingetPath = $ResolveWingetPath[-1].Path
}
$ENV:PATH += ";$WingetPath"
winget install microsoft.edgewebview2runtime --force --accept-package-agreements --accept-source-agreements
