GetVmId:318: CreateLxProcess: WSL 2 requires an update to its kernel component.

I get this error message while there is no update I could apply (at the moment). Also, my wsl2 setup runs without issues using the stock terminal.

I found out that there is one newer pre-release I could install. Same results:
c:\Users\x\AppData\Local\wsltty\bin>wsl -v

And now I installed the latest stable release as well. Same issue:

I can not reproduce the issue in my system running latest WSL 1.1.3.0.

CreateLxProcess: WSL 2 requires an update to its kernel component.

The error message is not from wslbridge2. Do you have any extra settings in wsl.conf or in .wslconfig file? Also, what is the output of wsl -l -v command? You can hide any personal information with foo, bar like words.

Nope, can't reproduce. Would you like to try the latest package from here https://github.com/microsoft/WSL/releases ? Uninstall the existing WSL before that. It'd not remove any Linux distributions in WSL, so generally safe to test.

Also, Which wslbridge2 version are you using and where did you download it from?

I use it as a part of wsltty. I does not start at all. I followed some issue descriptions and found that thi is where it fails.
I took version 1.1.3 from the WSL releases page. Seemingly it does not matter which version I use: 1.03, 1.1.2, 1.1.3 (see my comments regarding the versions I tried)

One quick workaround would be to install the msi package from that link https://aka.ms/wsl2kernel. It will install the Linux kernel in System32 directory. Generally it is not required with the new WSL from Microsoft Store.

Hello, I can reproduce this issue after applying KB5032190 with wsltty 3.7.0.
Uninstallation of the KB5032190 patch didn't solve this.

It seems that an undocumented COM API CreateLxProcess() fails.
I've reported this at mintty/wsltty#327 as well.

I have time to help you with analysis and actual fix PR.
Can anyone give me some tips?
