I have been in this situation before, and have learnt a lesson since then never to close the window and never to use 'save' but use 'apply' instead, use a incognito window and make sure I still am able to login before closing the main window.
That said, how about installing another version of Jenkins on another computer, use that config.xml, and try to restart jenkins? Then slowly make the changes that you had previously. You could even check the differences between the two and find the culprit. Sorry, that is not the best answer you were expecting but something to get by.
