Cubase crashing and stalling post 8.5.10 update

Hi guys.
My up until last update stable Cubase started crashing a lot recently.
Anyone else experiencing problems with that after the 8.5 and 8.5.10 updates?
I am a Windows 7 64 bit user, but also having someone I work with having similar issues on an Apple computer and system, and its been ongoing for months.
Is there a way to roll back the update without having to uninstall everything?

Needless to say, deadlines are tight and this is killing time to often.

Any help would be greatly appreciated.
Yes I contacted Steinberg Support, however as this is a time sensitive issue I figured asking here might be faster in terms of getting a response.
