The most likely cause is that Microsoft has changed the authentication logic of the free Edge-TTS interface. The Sec-MS-GEC signature mechanism has been updated, so calls sent by the old version (v4.15) are rejected with a 403 response.

Solution (in order):

Upgrade to v4.16 or later. The v4.16 update already fixes the Edge-TTS 403 error. Download the latest patch package and overwrite all files in the old version, including the sp.exe, _internal folder, and videotrans folder. Your JSON configuration files will not be lost.
If you are deploying from source, run:
uv add git+https://github.com/rany2/edge-tts.git
If that fails, run uv remove edge-tts first, then run the command above again.
If you still get a 403 occasionally after upgrading, it means you are being rate-limited. Open Menu → Tools/Options → Advanced Options → Dubbing Settings, set EdgeTTS Max Concurrency to 1, and set Post-Dubbing Delay (s) to 5~10.
If the error is caused by the proxy, create an empty file named edgetts-noproxy.txt in the software root directory (D:/Install/Video_translator/win-pyvideotrans-v4.15-1/) to force Edge-TTS to bypass the proxy.

Additional risk (not the direct cause of this error, but it will cause failures):
Your video path C:/Users/pbank/Мой диск ([email protected])/.../20_Filters open Area and Date.mp4 contains Cyrillic characters, spaces, parentheses, and @. The later stages of FFmpeg muxing are very prone to crashing on this kind of path. It is recommended to move and rename the video to a shallow directory with only English letters and digits, for example D:/videos/video1.mp4.
