Problem with game source

Hi, I’m using ManyCam Studio on Windows 10, and I’ve tried adding several game sources. When attempting to connect to Overwatch or Mini Metro, ManyCam actually crashes; when attempting to connect to World of Warcraft it shows just blank snow/static, and with AirServer I get snow/static with the caption “Video source is ready. Waiting for game to launch” even though AirServer is running and the Windows Game Bar sees it (I’ve checked “Remember this is a game” with AirServer too).

TBH AirServer is the most important one to me, I am trying to use it for work, to share my mobile devices’ screens with my colleagues… but the fact that WoW, Mini Metro, and Overwatch misbehave too suggests that something is amiss.

Any suggestions would be appreciated.
