Kerbal Space Program

Ok, I played several hours (about 4/5) without any problem the day before yesterday, then yesterday the crash came after each mission. Long or short mission get the same result : unable to use the X button in the VAB. I tried to come back to the space center : nothing more, to the mission control : same, to the tracking station : same again, to the main menu and back in the game : no way. The only way to use properly the X button in the VAB is to close the KSP ap' in the PS4 menu, then launch it again.

Well, my career mode is on it's way without any new crash, and I would like to make some test before do them in career, so I went to the sand box, and then, the game crash again, three time in one hour. So I supposed that the game don't like new saves, then I try another career mode, Crash again... I think so the begining of a new game crash, but after some progress, it doesn't. (Try to document the best I can)
