Network Device error in Ubuntu 22.04 LTS (WSL2) when doing network setup with Powerscript

My company provides some network tweaking scripts to update the WSL network stack to work together with our internal network / corporate proxy / etc.

The part of the powerscript which is problematic in my case is here:

Write-Host "Attach static ip to the wsl2 interface"    $ips = (wsl -d $wsl_distro -u root bash -c "ip addr show eth0 | grep inet | cut -d '' -f6").Split("`n")    $broadcasts = (wsl -d $wsl_distro -u root bash -c "ip addr show eth0 | grep inet | cut -d '' -f8").Split("`n")    # Remove all IPv4 addresses    for ($i = 0; $i -lt $ips.length; $i++) {        $current_ip = $ips[$i]        # Don't touch IPv6        if ($current_ip -notlike "*:*") {            # If it's not the static WSL IP, it's the currently generated dynamic IP            if ($current_ip.Split("/")[0] -ne $wsl_ip) {                $dynamic_ip = $current_ip                $dynamic_broadcast = $broadcasts[$i]            }            wsl -d $wsl_distro -u root ip addr del $current_ip dev eth0        }    }

This line here

 wsl -d $wsl_distro -u root ip addr del $current_ip dev eth0

gives me this error

RTNETLINK answers: Permission denied

A dedicated call gives me the same, of course (e.g

ip a del  169.254.228.65/32 dev eth0RTNETLINK answers: Permission denied

)

Here are some system data:

Anyone has an idea what I could try?
