Thank you @richylyq.

Looking at the logs, the issue is that WSL2 failed to create its network:

@keith-horton: I see this logline:

Just before the failure. Any hints on what could cause that ?

hey @OneBlue
Thanks for checking up on the issue! Much appreciated!
I ended up resetting the PC and it resolved the problem. Marking the issue as resolved 🚀

[keith-horton]

Sorry, that's an odd error to show up there. I would need to get hyper-v traces to see where it failed.

[OneBlue]

@keith-horton the logs should contain the hyper-v traces.

Let me know if any other trace providers are needed to diagnose issues like this
