Premier pro latest version crashing

No issues with this software for at least 2 year until recently

1. I called adobe support for help nothing they can do,I did perform a trash prefs, and cache. Running a 2013 macpro with alot ram(32 gigs). 

2. Crashing started happening whenever I upload raw footage from my  cannon 200 then when mixed in with other cams. Blade tool, cutting, ripple deleting, scrubbing, etc it will crash.

3. This morning it would crash from working on normal project with my other cameras.
