Always getting an empty white window when starting nw.exe

Question

I have problem with NW.js, when I run nw.exe or my project directly in cmd "nw.exe ./path/of/myApp", NW.js doesn’t work. I always get an empty white window. See this animation:

Note: my cursor always loads by interval when the NW.js window is active. I’ve waited 5 minutes but the program was not loaded.

But 10 minuts before, NW.js worked correctly. Now, after reboot, the problem persist.

I use NW.JS SDK 64bits (lasted version online).

I have tried with NW.js Stable (not sdk) but I have same problem.
