Crash FCPX

Hello,

FCPX 10.2.3 (276640)
A couple of months ago began to crash. One day it did not start at all, then it could only run in safe mode.
Now like it is launched, but crash every 10 minutes (if work, if not work - not crash).
Error report docs.google.com/document/d/1aTeMEWC-HodO...c6CTLazjPYSoFT8/edit

I do not want to upgrade to the new version. I need to finish a complex project first.

Can something be done without risk for the current work? Or FCPX to rearrange without a replacement version, or something else.

ps. I think that this is due to the fact that I cleaned the library - I move folders to the external disk. Maybe because of the fact that many times there and then these folders chased, now buggy. Or, bcz OS and FCPX was used mercilessly 2 years without renews .

Help, plz

Hold the Option and Command keys together while launching FCPX, and delete the preference files. See if that will help.

Running Disk Utility to repair all drives could help.
