Cubase 8.5.20 crashes while I try to save the project


After installing latest El Capitan update (10.11.6) I have problems working on certain projects. Not on all projects, but on a particular one. Suddenly Cubase crashes in the middle of work. Sometimes it doesn’t even load up to start working.

I had similar problem on the previous update (10.11.5). But after a while the problem vanished on its own. Now with the newest update the same problem.

Some solution? I go crazy, can’t work anymore.

BTW Cubase often crashes while I try saving the project (ctrl + S).
