Final Cut Pro start freezing all the time

I bought and use fcpx since more than one year and never have any problem until last week. Any of my project always freeze for now reason. Nothing change on my setting. I use the same hard drive as before. I try all the solution I found online, event removed Google Chrome and lost all my usfull setting on that app. But fcpx still crashing and I cannot find new solution to try...

I hope sombody can help me here because I have a lot of editing to do and I loose a lot of time because of that issue.
