Speaker cannot be heard when he/she shares screen in Jitsi video calll

Dear community, I have desperately been looking for a solution to the following problem in Jitsi video calls. It all works well up to the moment where someone shares his/her screen. From this moment on, I cannot hear any more the one sharing its screen, but all others conference participants. What can I do?

Can you upload the js console logs from such a problem session, from the browser of the participant sharing the screen? Thank you
