视频转文字后的chat功能不能用

Describe the bug
视频转文字后，希望通过对话方式问答了解视频内容，但每次点击chat，都只是闪动一下就没有反应了。在错误日志中有显示，错误显示如下:

The error in log shows as following: "[error 15:50:21.712] Error occurred in handler for 'embeddingTranscription': Error: OpenAI or Azure OpenAI API key or Token Provider not found

OpenAI 的API已经设置，并可以正常汇总和mindmap

Additional context
Add any other context about the problem here.

Start with the embeddingTranscription handler named in the error and trace it from the bundled dist-electron/main/index-26a191c4.js stack path. Check why chat cannot find the configured OpenAI or Azure OpenAI credential even though summarization and mind-map features work on Windows 11; done means clicking Chat produces a usable response without the credential error.
