Bug Report OBS Turns Sound off and Freezes after 10-30min Recording

[T-Rex91]

I'm not sure if Obs is the Problem or the new Windows Update because if i read this it seems M$ made a big mistake. But My Problem is if i Capture a Game like ETS2 or Little Inferno I can Record 10-30 min of the game. After that my Record has NO SOUND and I also can not hear anything at this moment. I Have to quit the game, Disconect my USB Headset and do it all agian. Here is my Report.
This crash appears to have occured in the 'c:\windows\system32\kernelbase.dll' module.
