app closes immediatelly

I was playing around with some code to learn, very simple stuff (Im learning)
a couple of arrays and a pushbuttocontrol…then I caused a bug for datatype mismatch and even if I removed that line
now the app closes immediatelly, no messages, nothing.
It runs and closes so fast it seems it doesnt even open.
No error messages nor warnings.
I already tried to restart xojo and restart the pc in case it was a bug. But nothing changes.

It behaves as if I put a “end” command in the windows1. activation event…

What could it be ??
thanks for yr help

Perhaps you could share your project so we can take a look. It doesn’t matter that you’re learning, as a general rule we all try to help and won’t criticize your code.

is it possible to attach files in the forums ?
Anyhow I’m afraid its a bug cos I removed all code and left just the controls , 1 pushbutton and it’s the same…

Looks like something is corrupted. If I where you I would stop waisting time and create a new project.
