Since a few weeks I enjoy the display mirroring with the desktop app, but today the service suddenly crashes when clicking on the sreen mirror icon in the browser. All other functions work fine, but as soon as I try to open the screen mirror page, the windows system tray services crashes and shuts down. Trying to solve I updated my windows (v1903) and I also updated the firmware of my panels. Also tried another browser. Nothing helps. I tried on another PC with Windows 10 (v1909) and it works fine. I really don't know why this problem suddenly occures. Please help, this is a pitty.
