the video window may close unexpectedly in the middle of a sentence

Hello. Sometimes the video window may close unexpectedly in the middle of a sentence when the assistant is saying something. If you start talking yourself, so that the assistant begins to regenerate the text and voice it, the window will appear again. I found out that this is a bug in `silly_extras.bat`. It wants to open a wav file, but can't. Any ideas why? ``` cv2: missing video frame Exception in thread Thread-4 (wav2lip_server_play_init): Traceback (most recent call last): File "D:\miniconda\envs\extras\Lib\threading.py", line 1045, in _bootstrap_inner self.run() File "D:\miniconda\envs\extras\Lib\threading.py", line 982, in run self._target(*self._args, *self._kwargs) File "D:\talk-llama-fast\xtts\SillyTavern-Extras\modules/wav2lip\server_wav2lip.py", line 342, in wav2lip_server_play_init next_video_chunk_global = play_video_with_audio(video_file_path, audio_file_path, True, next_video_chunk_global, rand_caption) File "D:\talk-llama-fast\xtts\SillyTavern-Extras\modules/wav2lip\server_wav2lip.py", line 475, in play_video_with_audio wf = wave.open(audio_file, 'rb') # Open the next audio file File "D:\miniconda\envs\extras\Lib\wave.py", line 631, in open return Wave_read(f) File "D:\miniconda\envs\extras\Lib\wave.py", line 283, in __init__ self.initfp(f) File "D:\miniconda\envs\extras\lib\wave.py", line 274, in initfp raise Error('fmt chunk and/or data chunk missing') wave.Error: fmt chunk and/or data chunk missing 1718026936.074945 in wav2lip gen server chunk:23_2 in wav2lip_server_generate: is busy: 0, face_detect_running: 0, chunk: 23, chunk needed: 23, reply: 2 ```
