Hi.
I have a problem with OBS studio. After I add a new scene with my webcam Microsoft LifeCam HD-3000 OBS Studio will become unresponsive and also will freeze my computer having my to shutdown from the power button. If I reinstall OBS Studio and use no webcam, no scene, everything works okay, but after adding new scene with webcam OBS freezes my computer again.
Here is the log file with scene and webcam added:

I managed to fix the problem. Because I use a laptop I have 2 video cards and when i start OBS Studio my AMD video driver was causing the system to freeze
LKD_0x141_Tdr:6_IMAGE_atikmpag.sys
. I disable AMD driver and OBS Studio is working fine now!
