I have a very large model (too large, I understand my mistakes in creating this) which has a lot of the data in the Data Model. I tried to close the Power Pivot window and it attempted to autosave and update PivotTables, it has been stuck at 0 progress on this for about an hour, see attached photo. I have tried mashing esc, I have tried CTRL+Break, I will disable automatic update and calculation when I regain control of the program, but I cannot get it to stop the save/update process which is CURRENTLY running. I cannot just end the task because then I will have lost hours and hours of work. How do I cancel the save process so I can restructure the model to be more efficient before attempting to save/update again?
