Question / Help My window capture is a blackscreen

[Vocalism]

Hello,

I want to record a game (League of Legends) and it has a seperate launcher and the actual gameclient. However, when I try to capture the gameclient while actually playing I only get to see a blackscreen.
Here are my logfiles:

Edit: It worked just fine before the last windows update

Any help is appreciated! thanks

Does Game Capture work on the League game client?

No I also get a blackscreen there. But even if it worked I would prefer to use the window capture because for me it was less laggy and smoother overall.
