What Mac operating system?
If you open a new project, do you run into this problem?
What are you doing now...trying to open an existing project that was saved closed, and, when that fails, you try to open the project's AutoSave(s)?
Please give more details.
OS: El Capitan
New Project: Created the new project, added media etc., saved, closed, re-opened ... Ok
Made changes, saved, closed, repoened from Finder ... OK
The one that is crashing:
Created with PE11 on Yosemite <Changing as many variables as possible>
I made a small updates, saved, closed, try to reopen and it gets to 100% then everything closes
I restore, try saving with no changes, crashes on reopen
I've tried auto save versions, same result
I tried uninstalling and reinstalling PE & PS. No luck (Not sure how clean the uninstall was since the recent list was still populated)
