vst mic assigning doesn't work after adding external hard dr

After adding an NAS"backup hard drive" to the mac, It seems cubase no longer has my vst assignments? I tried connecting a mic to my 824 interface but cannot route it to a channel? I’m not sure this has anything to do with it, but I also see "studio Not Connected in yellow at the top? can anyone tell me how to set my vst so I can record again?

Hi and welcome,

Make sure your Audio Device is still selected in the Device Setup > VST Audio System > ASIO Driver.
