Good afternoon, once again I come to the forum, the first time I did not get any response. I use veyon in the classroom for several students, after updating to version 8.4.1 for some users I started having problems viewing the screen from the master veyon, the screen turns orange, and does not come back, not even restarting the service, only reinstalling the program and when turning the machine off and on again the same error happens, on the other machine I updated it and it started to have a black screen, it only returns by restarting the service, I tried several things already and none of them solved the problem. An observation even going back to the previous version of veyon does not work in any of the cases Help Me @tobydox
