Issues with Kontakt Player loading

Developer VST 3 SDK
1

My own VST3-SDK-based host can successfully load and run several plugins. But on Kontakt 8 Player it simply does not correctly open the edit controller.

the debug output in console shows:

[2024-10-27 23:06:01.951] [info] initializing… 2024-10-27 23:06:01
[2024-10-27 23:06:06.805] [info] initialisation complete: 2024-10-27 23:06:06
cannot resolve resource: resources_DEU
cannot resolve resource: lib_DEU

Is there a specical requirement for that plugin?
Any suggestions are appreciated.

Thank you!

OS: Windows 10 Pro 64bit 22H2
Same problem also happening with Kontakt 7 player.
In other DAWs the plugins correctly show up and load.

When opening the plugin view on Kontakt 8 player
view->getSize() returns -2147418113 (8000ffffh)

The VST3 SDK indicates such a situation as a fatal error:

And so did my host, but did not correctly setup the window controller.

So now I use:
plugViewSize.left = 0;
plugViewSize.top = 0;
plugViewSize.right = 730;
plugViewSize.bottom = 600;

And the Kontakt 8 Player correctly shows up !
Also some exceptions occurred. I reported all of this also to NI.

Solved!
