RPG maker VX ACE playtesting doesn't work

I've been working on a project for a while and the past two months I wasn't able to use my computer, when I finally had the time to, when I tried to play test the game, the window opened, stayed black for a while then shut itself off again. no message. nothing. just that. I tried to open it again but from the 'Game.exe' and It did the same thing. When I tried to do it with other projects that I had, It seemed to be working just fine. I looked if there was something missing from the game folder but everything was in place. I tried reinstalling RPG Maker VX ACE but it still did the same thing. I tried to search about it but the person that had the same issue was with RPG MV. I'll be very appreciative if someone could help, thank you.

I have seen this a few times and it always seems to be different. If you can open a second project without issues, then while you are in that project can you click file->open to open your problem project?

Yeah

have you changed anything in the scripts?
Especially if other projects work without problems, behaviour like that indicates that some of the scripts are broken - the game.exe is nothing but an interpreter for the game code, which is mostly in the script editor with only parts of it in the DLL.

It depends on how long the sequence with the black screen is. If it were a problem with the game.exe (for example an antivirus blocking it), then it will go down within one or two seconds. If it stays longer then the game code is alreaddy being processed and the cause is in the game itself.

Does yeah mean you can do it, or you tried and it didn't work?

Yes, I can do it and it's working fine

No, I don't mess with the scripts, I do add new ones but they worked fine before and they work fine in other projects.
and I did turn off my anti virus and tried to open the game again but nothing changed.
I checked the game files and nothing seems to be missing.

If you enable the console (via the Game menu) and test play, does the console appear and are there any messages there before it all closes?

Yes. I does appear and no, no messages appear before it closes.

Yes. I does appear and no, no messages appear before it closes.

are you using the steam version or the standalone version? There are several differences where a steam-based effect can cause problems in Ace, and then you'll need additional steps to repair the problem.

No, I'm using the standalone version.

Did u accidentally delete 'Main' from your script slot?

I just looked and at first everything seemed normal but apparently this code "rgss_main { SceneManager.run }" was missing and I didn't notice anything about it before since I don't go near main(I think it somehow was removed when I wasn't on the computer?),but It's working now. Thank you and I apologize for the trouble.

if your problem is all sorted, please report your first post and ask for the thread to be closed. The mods will see it and take care of it :)

alright, thanks
