Creating your own MainWindow is an odd workaround. $poe_main_window should be defined there, so your MainWindow->new() call should never happen.

If you do succeed in creating your own MainWindow, you may notice that clicking on the close button doesn't stop your program. You can re-enable this with POE::Kernel's signal_ui_destroy() method.

There's no good reason for JSON::XS to interfere with Tk, but perhaps there's something conflicting at the XS level. Have you tried a non-complied JSON library instead?

If it is a C-level issue, then also be sure that you're deploying the software on a compatible version of Windows and C's runtime libraries. I'm not sure whether perlapp bundles things that far down.
