Looks like
Version 156.0.4285.0 (Official build) dev (64-bit) is also affected.
In my case, When Twitch playback switches to 1440p on some streams (toggle) it sends HEVC, and Edge Dev 155's hardware HEVC decoder (the DXVA/Media Foundation path) fails within milliseconds of starting, and since there's no software HEVC fallback, playback dies and Twitch shows Error 3000.
