oh no! I hadn't experienced that in beta testing so I need to dig deeper, is there a specific program (like Windows Defender or a different antivirus) blocking it? Does it give you the option to whitelist the file or ignore the warning? Sorry for the trouble!
It might be the lack of code signing on my raw exe and/or the way I built the Game Maker project straight to exe. I just built, tested, and upload an installer file for Solumnoid instead of a plain exe (the installer is still an exe but hopefully it will be treated differently). When you have the chance please try downloading and running Solumnoid 1.0 installer from this page and let me know if you run into similar issues.
