Comment (by John Dury):

 FWIW, I reverted back to an older build 05/05/2021 4.40 gyan.dev and it
 seems to not have this issue. I spoke with one of the source hosts (BtbN)
 and he said none of the x.265 code had changed recently so it must be
 something else.
 I also tried pasting the logs one at a time but there are too large for
 pastebin. Honestly I would be a little surprised if anyone looked at this
 since it is so odd,especially across builds and appears to only exist when
 using ffmpeg on some, not all, MKV files. I can consistently recreate it
 with the uploaded MKV and several of the newer ffmpeg windows binaries.
