Cubase Crashes When I switch to a workspace

Hi,

I have two external monitors with my iMac.

I created a global workspace: Project on the lower left monitor, score editor on the right monitor, and mix console on the top monitor (iMac). all of them are maxed to the screen ( via Ctrl+Alt+Return). I named it “Project Score Console LRT”)

  1. Open score editor on the right side.
  2. project editor on the left monitor.
  3. Call the Global workspace: Project Score Console LRT

Cubase crashes. I tried it several times each time Cubase crashes. All the crashes are related to the above issues within 10 minutes.
