these mono files hangs with ffmpeg's bonk decoder:

all of the files I shared so far were encoded with use of this converter:

for lossy files which I shared it's still possible that there is some bug in encoder and original bonk decoder is just more tolerant for the erros in the stream and can recover better from them, but this is just my theory (in case ffmpeg's decoder is really not buggy)
