Cannot load file or recording into Audio component.

Describe the bug

I have been using gradio cc create MyProject --template Audio to make custom components. It has been working fine for a while, but a few hours ago, I lost the ability to upload a file to the component. Whenever a blob is supposed to load into the underlying component, it throws an error.
I ran the above template command again in a fresh directory, with no code edits, and got the exact same errors. I then checked https://www.gradio.app/docs/gradio/audio#demos and, though I can't see the container logs in my console, the container crashes when I stop recording audio to the reverse_audio component, which seems like the exact same issue. The generate_tone demo works fine, and also the reverse_audio demo is the only place that I see a full on page crash. When running the dev server locally, it's just a no-op with some errors and an unplayable track with no waveform.

As of this morning, this was not happening as far as I can recall. Also, I had an old demo tab open, and the cached container could handle my recording, but the second I refreshed and it rebuilt, it started crashing.

I can reproduce this on my Mac (with Safari, and Brave) and WSL2 Ubuntu (with Brave and Microsoft Edge) environments. Have not tried Windows.
