Means that the program run out of memory (RAM). There was attempt to allocate memory for OBS source but nothing left for the application. Thus, it crashed.
Try to monitor memory usage RAM and VRAM via Task Manager. If some application consumes memory too much and its usage constantly grows then either application is written with errors (including some external component of it, as "plugin" you have installed yourself, for example) or you demanding too much from your PC. Also, it is possible that device driver (capture card, webcam etc) is bugged a bit - the crashed thread has traces of DirectShow device usage (usually, you see it as
Video Capture Device source in OBS).
