Cubase 8.5 Not Responding After Closing A Project

Hi everyone,
As similar to the issue that many users faced before Cubase becomes unresponsive and I cannot close it unless I open Task Manager and End Task.
I said “similar” because this issue is not solved by removing the tick on USE HUB selection in Preferences.

After closing the window of a project, Cubase hangs and I cannot close tha main screen of cubase.It is stuck after clicking the X on the right top corner.
When I open Task Manager ,I see the error as shown below :

Is there anyone knows what to do?

Thank you in advance
