The program does not open on windows 10, what should I do?

Question

.NET

Good day to all, I ran into such a problem, switched to windows 10 and the project that I wrote in C # does not open, I collect it in .exe, I launch it and everything, near the mouse icon, something happens, but it does not open it, I launched it on behalf of the administrator the same nonsense, uninstalled Visual studio, installed it again and again nothing, rebuilt the project many times - it doesn’t help, I even created an empty project, built it and it also doesn’t start, I can’t understand what is happening at all, VS is the newest 2015, Windows was licensed, not from torrents, and the seven that stood before that was also licensed, can anyone encounter such a problem? what to do in general? it just seems like a good system, but this nuance doesn’t suit me at all, since the laptop is for work, and if it doesn’t open the assembled program on it, then what for, then I need it, I’d better roll it out ...

Answer 1

Attach a debugger to the process and see what happens.
I would also enable developer mode, but I don't think it's critical.

Answer 2

First, disable the antivirus, I had this because of the use of the Costura.Fody package (adds dependencies as resources of the main exe) and Avast antivirus
