Would need to check more, at least locally it works, but apparently your setup seems to be on the "extraordinary" side in many aspects.

I guess you did use windeployqt? Which type of image is this? The libpng warning appears on multiple platforms and comes from upstream.

So you compile that on your own? There might be multiple reasons. First assumption would be capabilities (internetclientserver, potentially others). But also note that lots of the API, especially on networking, does not exist anymore for WinRT

Correct, hoping to have some time for that after 5.5.0  is out.
