8.5 project cannot load past mix console

Hi guys I’m running cubase 8.5 Pro on wndows 10 pc and all of a sudden I cannot load my projects !

They’re getting stuck during loading at the mix console load bar. It doesn’t seem to matter what project I load whether it’s an older project with full processing and plugins on it or one of my new projects that I have only just started tracking on.

Has anyone else had this issue and if so how was it rectified?

Cheers in advance.
