I have contacted all the other parties involved so I wanted to send this to vMix directly as well.

The Easy Anti-Cheat detection software that is very common in video games is flagging the vmixvideo.ax file as untrusted preventing starting gaming software using their detection. Please do what you can to work with them to stop these false positives making your software incompatible with any system protected by their software.
