1. I have used Studio for 72 hour+ streaming without issue, so I doubt it's on Studio's end (although it is possible).
2. You didn't post a normal log, but just a crashlog....
3. That said, looking through the crash log it looks like you're using QSV, which isn't all that reliable. That means:
4. Make sure that you're using the latest Intel GPU drivers. If not, please update.
5. Upgrade your CPU to something powerful enough to do x264, which will run for days without rebooting (assuming the rest of your system is able to keep up).
QSV isn't all that great for live streaming for a few reasons (higher bitrate needed to achieve the same quality as x264, a propensity to crash, etc.), so if possible please consider using x264, even if you have to put the x264 preset on ultrafast (which should give you similar quality to the QSV that you're currently using).
