We have been using OBS very successfully for over a year now, but very recently have been having many software crashes after 10-15 minutes into service. Haven't changed anything in hardware or setup. Only use one Canon Vixia HF G50 camera and capture card. Only streaming to Facebook Live. Laptop is dedicated with an i5 processor and 4G of RAM. CPU running at 50%ish. Not sure what to look at! My abilities are only average, but I can understand and follow technical instructions. Sorry I don't have a log file at this time! I will try to send when I'm at that computer. Just need some direction at this time of things to check.
