Cubase 8.5 crash when loading old cpr projects

Hi All,

I was using Cubase SX 2.3 on PC and now am recording on Cubase Pro 8.5 on MacBook Pro. When I installed my new Mac configuration a few months ago, I verified that my old projects could load in the new Cubase and it worked fine.
After working for a while on many new projects, I decided to reload old projects, and now Cubase crashes when activating an old project…

My config is the following :
MacBook Pro Retina 15"
Cubase Pro 8.5.20 64 bits
Mac OS El Capitan 10.11.5
RAM : 16 GB
Proc : Intel 2.5 GHz Core i7
Audio and Midi Interface : Focusrite Clarett 4Pre

I join an extract of the crash report hereafter and I thank you in advance for any help,
