During the AI-generation of a video using Kling 3.0 I submit the first frame for it and the prompt. The AI starts to generate the video, but after couple minutes it gives out an error, saying it is unable to download or show the created video. No credits are spent on the unsuccessful attempts. The problem is staying for 4 days now.
