Adobe Bridge freezing?

Using Zoom as host for meetings of 40 people (who have mikes and webcams turned off) I need to show photographs full screen using Adobe Bridge. I use the screen share and have turned other programmes off on my PC. Adobe Bridge freezes when showing photos full screen. I can only get it to work if I stop sharing, then re-share. Normally Bridge works perfectly.

My PC is an i7, Windows 10, 32GB RAM. It is connected by ethernet to my router and fibre-optic broadband. Speedtest measures my internet speeds as 36Mbps uo, 520 Mbps down. The photos are 2.2 megapixels max and the problem occurs whether I anm showing them from a SSD or a HDD.
