Inspecting wslsys seems to point towards the get_windows_uptime() and get_win_system_type() functions failing on my system

Can you try to type gcim Win32_OperatingSystem in your Powershell Core and post the result?

[tranzystorekk]

~
❯ gcim Win32_OperatingSystem
Get-CimInstance: Invalid class

[patrick330602]

This seems to be a issue on your side: https://techcommunity.microsoft.com/t5/ask-the-performance-team/wmi-missing-or-failing-wmi-providers-or-invalid-wmi-class/ba-p/375485

this WMI class should exist on Windows

[tranzystorekk]

had some time to look at this, doing (in an elevated shell instance):

net stop winmgmt
winmgmt /resetrepository

worked for me

I will include this in the F&Q for ref for people in the future
