Hi Carter, thanks for the reply.

I made a video demonstrating the issue, including trying the doubletap recovery process you linked. Hopefully this helps!

Thanks for the video.

I wonder if this is something specific to Mac OSX and the CP2104. There are a few known quirks. See here:

and also here:

Does any of that seem like it applies or helps with your setup?
