Gorn Vr Memelauncher

So there’s a game on Virtual Reality called Gorn. A person called Mememan created a project on Github called Meme launcher to modify the game. You have verified his work meaning it is trusted and safe, however when i install it my windows defender stops me from downloading it because it says it’s a Trojan virus. I read the Faq on the official discord and they said it was normal. I allowed on Windows Defender and I didn’t open it yet because I don’t want Trojan’s on my computer.

Is this safe?
