Dear KevinYYLai,
thanks for your quick response. Indeed, I read several posts in this forum before creating a new topic, so I found the hint for activation of the front cameras already. Yes, all three check signs are there and I get a live preview of both cameras in the SteamVR app.
I tried the precompiled binaries of the C Sample code in v.0.8.0.1 and v.0.8.0.2 both before compiling the source code myself. I get the same problems also with the precompiled binaries. The task manager tells me that the process is inactive and I can watch my RAM getting filled up to the max. Then the process crashes.
The log I provided in my first post is indeed the complete log. It just stops after the line:
[ENGINE_SEETHROUGH_0_DLL] [2018-11-27 12:17:15] [LOG] TurnOn
I am happy to share more information here if you have any idea where to look at. Thanks for your help in troubleshooting this particular problem.
