Error with Launcher

Hi,
I started playing on this server a few days ago, it has been working fine for me until now.

No ideia about what may be causing it.

Hello, 

a) Open Control panel -> Programs and features -> on the left side of the window press "Turn Windows features on or off" -> disable "Virtual Machine Platform" and "Windows Sandbox" features.
b) Enter BIOS/UEFI and switch off the VM feature.
