Playtest error

[Saydas]

So, I'm pretty new to this anyway, i don't really know if I'm doing everything right anyway...

But

I downloaded the trial to try RPG Maker MZ out, and i'vee just been going through the tutorials. However, whenever I try to playtest, it'll let me a few times (maybe) before saying there's "nw.exe - System Error"

i'm not particularly tech savvy, so i'm just confused.

two main possibilities:
either the path where you stored your projects does not follow the networking rules required for HTML5 games, or one of your protection programs had a false-positive and is blocking that exe.

networking rules means no spaces, only latin letters and a few other restrictions.

and a lot of antivirus heuristics falsely consider MV to be a virus, because they only see the use of webtechnology to change local files (saving), but can't see that it is a local program instead of a remote website that tries this. You'll either have to update the virus definitions or whitelist RMMV in the AV.
