As host, my slide sharing view randomly disappears

Hi all,

Hopefully, someone can help. I am logged in to Zoom Webinar on a Windows computer as the Co-Host. When I share my screen and use PowerPoint, the shared screen disappears, and all I see is the gallery view. It has happened randomly, but it also happens when I click into the attendee pane while I am sharing slides.  I have a very hard time getting back to seeing my slides. The attendees and panelists see my slides even though I can't. I try resharing, and sometimes it works to get back to being able to see the slides. Help.
