Can´t share my screen, no matter what

I tryed more than 5 times… after uninstalling and reinstalling it… checked all hardware and system requirements… screen sharing is not working… everything goes well untll I hit Ok button… then, nothing happens… Windows 10 2018 release…

Hi @Hyran_Godinho, could you please tell me what is happening when you are hitting the ok button? Could you share a screenshot of the issue or a screen recording so I can see what is happening exactly?
Could you also tell me what is your Operating system and your exact Prezi Video version?
