This issue can temporarily be worked around by launching the editor with the "-nosound" argument which will disable audio recording.

Steps to Reproduce
  1. Choose a really large render resolution (such as 9504x1872)
  2. Disable Windows TDR to ensure you can render large images without timeout.
  3. Make a very long sequence (ie: 27000 frames)
  4. Crash somewhere during rendering, ie: could be on frame 7000 or frame 14000.
  5. Note log spam before crash: LogAudioMixer: Display: Audio Buffer Underrun detected.
