The error AssertionError: No text to send to TTS API is raised by the gTTS library because one or more subtitle entries in your SRT file are empty—they have timecodes but no text content (or only whitespace/special characters). gTTS asserts that a non-empty text string is passed to it, so it fails.

Fix steps:

Open C:/Users/Admin/Videos/VideoTrans/Tái Sinh 7 Ngày Trước Tận Thế - Cô Ấy Thức Tỉnh Dị Năng Không Gian/vi_all_final - Copy.srt in a text editor (e.g., Notepad++).
Look for subtitle entries where the line between the timecode and the next index is empty—for example:
```
42
00:00:01,000 --> 00:00:02,000
```
(i.e., nothing after the timecode before the blank line).
Delete those empty entries, or fill in the missing text. Also check for lines containing only punctuation or numbers—gTTS will also reject those.
Save the file and retry the task.

Additional notes:

If you prefer not to manually edit the file, enable 清理已生成 in the main interface before re-running the translation. This will regenerate the subtitle file from scratch, but it also deletes the previous .srt file, so only use this if you're okay losing manual edits.
The SRT file must strictly follow the SRT specification. Since your filename contains - Copy, it may have been edited externally—ensure no stray formatting was introduced.
Consider switching to the default Edge-TTS(免费) channel instead of gTTS, as it is generally more robust and is the recommended default for most languages.
