Project Browser has disappeared

[avi10000]

Hi all,
Project Browser has disappeared from one of the EA instances I am running. When I open further instances they are also like that.
 
Instead of the Project Browser I get a line as follows:
    > / >  Model >

Hope you can see this image: https://ibb.co/p3JNjGm

I have searched the forum and have found some solutions for this question. So far none of them seem to work. E.g., here is a list of shortcut keys: https://sparxsystems.com/resources/user-guides/14.0/basics/keyboard-shortcuts.pdf. Says to hit Alt+0 to display Project Browser. But it displays the  Feature Matrix window.

Any ideas?

Thanks

Avi

You could try selecting the default workspaces to reset the layout.
Start>workspace layout
Select System Default
