This works for me.

Can you share Get-Error output from PowerShell 7. Please use latest build 7.1 RC2.

[datvm]

Sure, here's the output:

I guess it is specific for Microsoft Windows 10.0.19041.

[datvm]

There is no newer Windows 10 version I think. Do I need to report this issue to any other repo or you can tag them from here?

[iSazonov]

@datvm You could use Windows Feedback tool and other channels to report the issue to MSFT Windows team.
I will ping MSFT PowerShell team but I am not sure it is PowerShell issue.

[SteveL-MSFT]

Since the error repros in Windows PowerShell, it's not a PowerShell 7 specific issue. Agree with @iSazonov to use the built in Windows Feedback tool to report the issue so that the owner of that cmdlet can look into it.
