#6941 Video file selection required

The error "Video file selection required" indicates that at the moment you clicked "Start Execution", no valid video file was detected as selected.

Please verify the following steps:

1. Confirm a file is actually selected: Click the Select audio or video button (top-left) and choose a real file (e.g. .mp4, .mkv, .wav, .mp3). If you are using the Folder checkbox, make sure that folder contains at least one supported media file.
2. Check the file path: Ensure the video is not in a path with Chinese characters, spaces, emojis, or other special symbols. Move it to a simple English/numeric path such as D:/video/test.mp4.
3. Check the file extension and accessibility: Confirm the file actually exists and is readable. If you renamed it, make sure the extension is correct (e.g. .mp4, not .mp4.txt).
4. Try again: After confirming the above, reselect the video and click "Start Execution".

If the problem persists even after a valid file is clearly selected, it may be a bug in the file-selection state. In that case, please provide:

• The OS version and whether you are using the Windows pre-packaged version or source deployment (you already provided this: Windows 10, v4.11, frozen).
• The latest log file from the logs/ folder (copy the last ~30 lines of error information).
• A screenshot of the interface right before the error appears.
