Random failure on screensharing (works after hanging up and sharing again)

We are experiencing a rare issue where sometimes screenshare fails. Once it fails even video (camera) cannot be turned on. It works after hanging up and joining the meeting again.

We are running the latest Jitsi version on Ubuntu 18.04 (dpkg -l | grep jitsi output follows):

ii jitsi-meet 2.0.6293-1 all WebRTC JavaScript video conferences
ii jitsi-meet-prosody 1.0.5307-1 all Prosody configuration for Jitsi Meet
ii jitsi-meet-tokens 1.0.5307-1 all Prosody token authentication plugin for Jitsi Meet
ii jitsi-meet-turnserver 1.0.5307-1 all Configures coturn to be used with Jitsi Meet
ii jitsi-meet-web 1.0.5307-1 all WebRTC JavaScript video conferences
ii jitsi-meet-web-config 1.0.5307-1 all Configuration for web serving of Jitsi Meet
ii jitsi-videobridge2 2.1-551-g2ad6eb0b-1 all WebRTC compatible Selective Forwarding Unit (SFU)

We use Chrome as browser. I’m enclosing a copy of the browser’s console log in one of the failures:
