It still crashes when holding down the shift key when opening. There is an error log that pops up. I have removed any extra fonts that I had installed via Font Book...still the same thing happening. As for the boot drive? No idea...I have tried opening it from Application in Finder. Also have it on the dock, either way I am still getting the same result.
Here is first part of the error log:
