I tried testing with Godot v3.2.3 with all my previous projects and whenever I export them to an application through the "Windows Desktop" export template, the .exe isn't empty. ...But once I run them, this kind of message always pops up below. If I submit my entry when the jam has already started and this happens, am I allowed to send the folder with the resources that require the engine editor?
Why not upload an in-browser version? This message appears when (i guess) SmartScreen is turned back on after an update. Turn it off, or add exception. It worked before on your pc. Or maybe some export setting got screwed in Godot.
Nobody's gonna download extra things from anywhere else, put every requied things in the uploaded zip if you have to.
