Issue with opening Anki for the first time

I installed the latest versions of Anki (2.1.44 and 2.1.47) and none of them opened as an app. I can see in the taskmanager that it is running as a background application but it does not open as a program as it should. It also doesnt show me any error message so I´m a bit confused. For now I just installed the older version (2.1.15) which is surprisingly working but obviously I want the latest version to work with.

For some more information I started the application (version 2.1.44 and 2.1.47) in cmd.exe and here´s the debbuging info I got:

I really hope anyone of you guys can help me.
Cheers.

It’s probably a bug in the graphics toolkit Anki is built on. An upgrade is planned, and hopefully it will address this issue.
