1.4 Update killed Mautic :(

Updated to 1.4, and now it barely works… I can get around to some pages in the backend, like Contact lists, but if I try to edit a contact, the blue loading bar at the top just keeps going and going and never does anything. If I try to create a new landing page, I get an error that the file cannot be found. Try loading the plugins page, also get another page cannot be found. It seems that this update is missing files. Below is the current error log:
