Answer 1

I also encountered this problem today, but Holger's way didn't work on my situation. After consulting other people via internet, I finally fixed it. And my solution is quiet simple, I just open the Maintenance Tool and choose add components, select Qt Charts and Qt Data Visualization, and click next, and then it works. This problem happens because by default Qt Charts is not selected while installing Qt, so we should add this component manually.

But I also should mention that maybe this way just work on Qt which was installed by Qt Online Installer, and if you installed Qt via offline Installer, maybe you should reinstall it.
