Guid 56a868b3-0ad4-11ce-b03a-0020af0ba770 is IBasicAudio, fwiw.
Sounds probable. I played this particular match with the sound turned off (it happens regardless of this).
As the comment states, everything below these three lines (not inlcuding them) are probably related to the crash, as everything above and including these three are all posted on startup regardless.
