I googled around and it appears that false positives with rpg maker are common, you can see a forum post here where it's mentioned. https://forums.rpgmakerweb.com/index.php?threads/proving-your-game-isnt-malware-...
One commenter specifically recommends pointing people to use virustotal as a way to determine if any malware is actually present, so I ran my own program through it and only 7 of 66 anti virus softwares flagged any issues with none of them agreeing on what the issue is. This likely suggests it is indeed a false positive result. You can see the results yourself here or run the program through it on your own and come to your own conclusion.
