Taskbar blues

My top taskbar, Cubase 10.5 Pro, has stopped responding. How can I get it working. Windows 10 64 bit

Sounds just like a Cubase crash, without more details …
Normally stuff like that is resolved with restarting the computer.
Or at worst, start Cubase with the Alt button on to reset the preferences (I think it’s Alt..).

What is a top taskbar?
Taskbar is a term usually used for an OS feature.

I assume he means the menu bar which stretches across the width of the screen.
What the issue may be I don’t know.

The one that has File…Edit…Etc
