In my wsl2 installation the "ddev launch" command stopped working this week, because the xdg-open command didn't work anymore. Setting the $BROWSER variable to a specific browser didn't work as the standard installation path contains spaces and this breaks in xdg-open. Also it would break if I switch browsers or use a different standard browser.
