There is a reason this happens and I found out why a while back… If a settings window opens and only 1 group is available, then the entire window is closed because code exists to make sure both groups, and both files are open - if 1 is closed then both close…
Something, a plugin maybe, or a missing file… is closing one of the files being opened causing the issue.
Note: Since you are going to settings - make sure these files exist:
%AppData%/Sublime Text 3/Packages/Default/Preferences.sublime-settings
%AppData%/Sublime Text 3/Packages/User/Preferences.sublime-settings
The Default one may not exist, and that is ok in most cases because most people don’t extract the default folder - it should be loaded from the installed packages in C:\ or in the appdata … Installed Packages folder… ( It’s either there or in the Sublime text install dir )… The paths above will work on Windows by pasting them into explorer.
If you have to create a file in the User folder, set the default contents to:
{
}
and for the Default directory:
// Place your settings in the file "Packages/User/Preferences.sublime-settings",
// which overrides the settings in here.
//
// Settings may also be placed in syntax-specific setting files, for
// example, in Packages/User/Python.sublime-settings for python files.
