deadlock on Interop+Shell32.SHGetKnownFolderPath using -MTA/-STA flag

[MaxClaessen]

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

when running pwsh it gets stuck occasionally on some machines when using the flag(s) -MTA or -STA after investigations it gets stuck on Interop+Shell32.SHGetKnownFolderPath .
This happens even on a script that runs pwsh.exe -MTA -NoProfile -Command "$PSVersionTable.PSVersion.ToString()"
This does not happen on all our developer machines (Running Win 10 22H2), so far we have not been able to pinpoint the difference.

Can you try GetFolderPath and enumerate through the SpecialFolder and SpecialFolderOption to see if there is a specific one tripping your users up?

Eg (uses %% because it is in a batch file)

for %%F in (CommonDocuments,CommonProgramFiles) do (
	for %%O in (DoNotVerify,None) do (
		pwsh.exe -c "[System.Environment]::GetFolderPath([System.Environment+SpecialFolder]::%%F,[System.Environment+SpecialFolderOption]::%%O)"
	)
)

For instance is it looking for a network share?
