Cubase Element 8.0.40 Still showing Menu Bar When Exited

I’m getting a trange thing thats only just stated happening and wondering if anyone else is getting the same in whatever version of Cuabse they are using.

When I close Cubase it looks like it exited just fine except the menu bar is still at the top of my screen, If I open up task manager it appears that Cubase is still running and i cant kill the process the only way to get rid of itis to reboot the PC.
I’m running Windows 10 Redstone with a UAD Apollo Twin USB, I can only think something like a Windows update has caused this because it was fine until this week.

Has anyone else seen something similar?
