Disconnecting dual monitors / issue with gallery view

I started using the dual monitors option, using a TV as the second monitor (showing the participants in gallery view) and my laptop (showing the shared screen).

I add twice an issue regarding the sound of the shared document, and since I was in the middle of a meeting I decided to stop the dual monitor and stay with my laptop only.

When I disconnected the second monitor, I had the following problem: it seemed like both "screens" were on the laptop - the gallery view of the participants and the shared screen. Therefore, on the shared screen, I couldn't see the participants like in a regular meeting (there are only 5 participants).

Is it possible to fix the problem without ending the meeting and starting a new one?

Thanks
