WSL2 does not use Windows network with CreateInstance/CreateVm/ConfigureNetworking/HNS/E_ACCESSDENIED after applying Windows 11 Version 24H2 (KB5043178)

Problem

wsl: アクセスが拒否されました。
エラー コード: CreateInstance/CreateVm/ConfigureNetworking/HNS/E_ACCESSDENIED
wsl: ネットワーク (networkingMode Nat) を構成できませんでした。ネットワークなしにフォールバックします。

Looks like similar of microsoft/WSL#11980 (comment)

How to fix

1. Win+R => OptionalFeatures.exe

2. Toggle Virtual Machine Platform twice to keep the original value. No need to reboot for my case.

3. Fixed with changing the IP address.

   wsl: アドレス '172.N.N.N' を使用してネットワーク エンドポイントを作成できませんでした。割り当てられた新しいアドレス: '172.M.M.M'

Didn't work

• Toggling Windows Hypervisor platform did not fix my environment (Originally disabled)

Happened again. And isn't fixed with same steps.

Disabling the Hyper-V doesn't fix it for now.

Fixed with unexpectedly applied patch again? It has same ID KB5043178 but modified the timestamp...

KB5035942
