This issue was solved by power cycling the printer.. Not sure why it happened, and i figure its good to let this be here as i didnt get any hits on google.

Hello, We have a rather new UM3Extended which i have been using for about a month now. After changing filament today, im not able to start print jobs. The printer will run the pre print operations as it usually does (heating, levelling), but as it raises the bed to start the print job it will immediatly go to "Print finished". I got the logs and it seems to fail at "Exception in file handling"... I have tried with two different USB sticks (the one i usually use, as well as the one that came with the printer).
