Configurator will not open

[Silvervanman63]

I have installed Veyon 4.5.6 on a PC installed with Windows 10 Education Pro version 21H1, OS build 19043.1081.
Veyon Master opens and works fine, monitoring a room of 30 PCs. Veyon Configurator attempts to open, windows spinning timer appears, then the application disappears before the window opens. Re-installation does not solve the problem. If I re-install version 4.1.8 (latest old version on my system). I can open configurator and create rooms and configure authentication. Re-installing version 4.5.6 then gives a working and configured Master, however Configurator still will not open.

Does this still happen with the latest 4.5.7 release? If so, do you have the chance to go back the releases step by step and report which version was the last one that works for you?
