I have tried verifying game files, re-installing game files, re-installing Windows, increasing virtual memory. The computer is not overclocked in any manner.

Strongly suspect this is related to the addition of Steam in-game broadcasting, as libavcodec-58.dll is an FFMpeg DLL and the crashes began recently, along with the addition of Steam in-game broadcasting on 6/26/24.
