vshost32.exe has stopped working when I call the ShowDialog method of OpenFileDialog

I've a c# application, I'm doing a final test of it.

But now, a function which has worked everytimes until now doesn't work anymore!

I've a Button, when I click on it I want to browse files, I see the "Open file" windows, and an half second after, I got an uncaught visual studio error:

vshost32.exe has stopped working:

I'm sorry but the error is happening on a french localized computer:

My code is:

OpenFileDialog ofd = new OpenFileDialog {Filter = Filters};
if (ofd.ShowDialog() != true) {
    return;
}

it crash just when I'm in the ofd.ShowDialog.

Is this a code related issue?

Do you have any idea about how to debug? Or even how to debug this??

When activating the "unmanaged code to be debug", I got this:

"First-chance exception at 0x77cd631f in TOM.exe: 0xC0000008: An invalid handle was specified."

The stack trace if it could help:
