From MDN, in the page you linked in your question:来自 MDN，在您在问题中链接的页面中：
NotReadableErrorAlthough the user granted permission to use the matching devices, a hardware error occurred at the operating system, browser, or Web page level which prevented access to the device.
This is a problem that happens between the browser and the device.这是浏览器和设备之间发生的问题。 It might be because of the driver.可能是司机的原因。 Your example works for me (not in the Stack Snippet), so I can't tell you what's exactly happening and how to solve it.你的例子对我有用（不在堆栈片段中），所以我不能告诉你到底发生了什么以及如何解决它。
I would recommend you updating your drivers.我建议您更新驱动程序。
