I fell for this scam from an acquaintance in a game dev community. After securing everything I found out that this kind of scam has been going on with different names, but "Yusumonis" shows up nothing on google, so I decided to post this for anyone searching.
A game dev friend dm'ed me in discord asking for a coop playtest for their friend. I agreed and downloaded the game (remote access trojan) and ran it after scanning it with microsoft defender with no threats found. I quickly found out that I was hacked, immediately deleted my discord account so that it couldn't be used in the same way, started an offline scan and disconnected from the internet. Logged out of all internet accounts on all devices with my phone and reset passwords. After looking up info online about it I'll reinstall windows with format before connecting to the internet again on my computer.
