whisper && ffmpeg translate error conversion failed!

[jc9090kkkk]

I was using whisper smoothly before. Yesterday, for some unknown reason, it suddenly stopped working. I tried to check the error message, but still couldn't figure out the specific cause. I don't know if it's a version compatibility issue. My python version is 3.9.9. The version of ffmpeg is 7.1.1. My computer chip is an Apple M2. Below is the specific error message. I wonder if any expert can help locate the problem：
Traceback (most recent call last):
File "/Users/sam.jia/.pyenv/versions/3.9.9/lib/python3.9/site-packages/whisper/audio.py", line 58, in load_audio
out = run(cmd, capture_output=True, check=True).stdout
File "/Users/sam.jia/.pyenv/versions/3.9.9/lib/python3.9/subprocess.py", line 528, in run

The above exception was the direct cause of the following exception:

Conversion failed!

I tried reinstalling python, ffmpeg, and even whisper. After installation, I tried to use them, but still got an error!

[jc9090kkkk]

But I found a very strange problem. For the files I had translated before, when I tried to translate them again, the whisper command displayed normally. However, when I tried to translate new files, it kept reporting errors. Could it be due to caching?
