#5824 Default role required

This error typically occurs when the Dubbing Channel is selected but no voice role is chosen in the Select Voice dropdown. Please ensure you have selected a specific voice role for the chosen TTS channel (e.g., en-US-GuyNeural for Edge-TTS). If the dropdown is empty, verify that you have correctly set the Target Lang first, and that the TTS channel supports that language.

If the issue persists or does not match this scenario, please provide the relevant log file. The logs are located in the logs/ folder under the installation directory. Copy the last 30 lines of the latest log file and paste them here for further analysis. Also, confirm the exact step where this message appears (e.g., when clicking "Start", or during the dubbing phase).
