Hello,

I'm having this issue with my WSL, that causes it to crash.

There was a precedent issue, that has no response : https://github.com/microsoft/WSL/issues/12433.

I have these logs in syslog, from the WSL :

This appears to be an issue with the wsl-pro-service malfunctioning, I would recommend filing a bug there for that team to address.

In the interim you can uninstall the Ubuntu Pro client with sudo apt remove ubuntu-pro-client.

Hello,

I'll try to remove the app. I don't think I really need it to get my WSL work.

Thanks.

Let us know how it goes. No, it is not necessary for Ubuntu to work on WSL. If issues continue, I recommend opening an issue on wsl-pro-service.
