I can't hide Cubase on Mac

I can’t hide Cubase Pro 11 from the shortcut (Command+H), from menu bar and from Dock menu.
I can hide all of other applications. Only Cubase is not hided.

Cubase 11 Pro 11.0.10
Mac OS 10.15.7

Did you ever find a solution to this? I had the same problem with Cubase 10.5 and the earliest versions of 11. After 11.0.20 the hide feature started working again. Bow today without warning I can no longer hide.
And did/does yours do this: When I Command H with Cubase up, the Cubase screen flashes away for an instant and then comes right back up. Only, it’s actually in the background because the mac “Finder” bar is now on top.
If you figured out why this is happening, please let me know. There doesn’t seem to be a lot of discussion about it.
Thanks
