### Category of the issue

Installation issue.

### Brief description of your issue

Installing Microsoft Office from an import `.json` file results in an empty setup shell that shows no progress

### Steps to reproduce

Create an import file with the following contents:

```js
{
"$schema" : "https://aka.ms/winget-packages.schema.2.0.json",
"CreationDate" : "2025-07-03T08:44:18.732-00:00",
"Sources" :
[
{
"Packages" :
[
{
"PackageIdentifier" : "Microsoft.Office"
},
],
"SourceDetails" :
{
"Argument" : "https://cdn.winget.microsoft.com/cache",
"Identifier" : "Microsoft.Winget.Source_8wekyb3d8bbwe",
"Name" : "winget",
"Type" : "Microsoft.PreIndexed.Package"
}
}
],
"WinGetVersion" : "1.11.400"
}
```

and run `winget import -i `

### Actual behavior

The setup.exe screen opens and shows a moving progress bar in the tasklist, but no progress is seen.

### Expected behavior

Microsoft Office is installed.

### Screenshots and Logs

_No response_

Start by reproducing the issue with the supplied import JSON and the `winget import -i ` entry point on the stated Windows environment. Compare the import behavior for `Microsoft.Office` with the expected installation flow, using the available winget logs if needed. Done means the import installs Microsoft Office rather than leaving an apparently inactive setup shell.
