Where can I see error log?

I installed Insider Preview on two computers and tried WSLg. One works perfectly, but another one doesn't.

Can I see any logs to research solution? I checked Windows' Event Viewer and wsl --system. But I couldn't find anything.

There is the /mnt/wslg/weston.log file. Also the wiki is a good start for diagnosing WSLg issues:
