Qt Widget "Library not registered" application error

I just started working with Qt and created a simple Qt Widgets program. When I create and run the application (even if I create a new project without new code), I get the following error messages:

mincore \ com \ oleaut32 \ dispatch \ ups.cpp (2128) \ OLEAUT32.dll! 74445072: (calling: 7444FE4F) ReturnHr (1) tid (188) 8002801D No library registered. (2) tid (188) 8002801D The library is not registered.

My Qt install and Windows are updated. I searched for a solution for a couple of hours and I can’t find anything even remotely related to a problem on the Internet ... Has anyone else had a similar problem?

Update:

I just completely removed Qt from my PC and made a new installation, and I still get the same messages.

Ugh. This problem hurt my sunday.

I am on QT 5.9.1, Windows 10, Surface Book.

I tried reinstalling windows, did not work. I tried reinstalling Microsoft Runtime, did not work. Reinstalled QT in millions of different ways, didn't work.
