camera access problems

Hello,

I use Jitsi from a Windows PC via a browser and since yesterday I can no longer access the camera (tests on chrome, firefox, edge). The only solution that seems to work is, via chrome, to revoke jitsi’s permissions and relaunch the page … The app asks me to re-grant the rights and the camera works for this session … Do you have to start over each time? Can you help me please?
