Problem with working at 48khz

Hi Steinberg community, I have a big problem. I am using Dorico with videos and so I am working with 48khz of sampling rate, but at a certain point (not immediately) it changes me the pitch of every note. This never happens when I’m working at 44,1 khz. Can you explain me why? What can I do?

What other programs do you have open?
It sounds like another program is taking control of the audio driver and changing the sample rate.

Zoom, for virtual meetings

Maybe change Zoom to 48kHz also.
