I'm sorry to hear that! Only thing I can suggest is to unblock it, as I have no way to test atm. Right click the .exe, go to properties and uncheck the scary looking message. (trust me, it's even worse on mac :D). No idea why it would just be my app, this is a straight up Godot export. I'll make sure to have my PC back up and running by next jam, this has been frustrating. No joke, my cat threw up on it and fried it. $12k doorstop right now.
Thank you very much for at least trying, I hope you get it to work!
