Problem saving files

When I want to save a score, I click save and I get this on my options (W10 explorer of my PC).
BUT there are drives missing completely,(ie. not showing) where I need to save my scores.
See pic “dor”

The second pic. “PC” shows how my actual W Explorer actually is. None of those drives are “hidden”, and I can save in them from any other App/software, except Dorico and Cubase.

I did have a home server installed in my machine, (fed up with the endless synch problems of one drive for business.)
What worries me is that all my programs work just fine, they can all read my W Explorer properly when saving or opening files, EXCEPT Steinberg´s Dorico and CUBASE. Wonder if reinstalling both from scratch could help.
Tks in advance.

Try run Cubase as administrator.

I can only run Cubase and Dorico as admin.
