Play Test Does Not Work

[Metha]

Hi!
I'm new to RPG Maker, and currently I'm doing some project on RPG Maker MV ver 1.4.0. I have created characters, classes, skills, items, and enemies. But when I try to play test it, the box pops out but it's all black. And then the stop working message comes out.
I have reinstalled it, but it's still no use.
Can anyone help me solve this?
Thank you.

Probably a problem in your side.
Did you add any code?

Most likely your AntiVirus or a similar programs blocks execution of the game.exe believing it to be a virus, because it uses HTML5-functions in local files.

If this is really the case, the programs should have logged its action. Check wich one has a game.exe as a possible virus and whitelist it there.
