Solo Tap v1 Won't Enter Bootloader

[troysandal]

I've been trying to update the firmware of my Solo Tap v1 but get the following error:

Wrote temporary copy of firmware-4.1.5.json to /var/folders/f9/tr02f6zj6sz4104bd_r35yfw0000gn/T/tmp275qpicm.json
sha256sums coincide: f36bb365bfddf75004f28af392ae1439192ca0ed821ef496084a75a00d05087a
Switching into bootloader mode...
using signature version <=2.5.3
erasing firmware...
Could not switch into bootloader mode.
Please put key into bootloader mode:
1. Unplug key
2. While holding button, plug in key for 2s

I tried holding down the buttong for 2s but it won't start flashing. I have a backup key that I tried this with and it works fine, so it's clearly something with this key. I tried entering bootloader mode via the following command but still no dice.

➜  bin git:(main) ✗ ./solo program aux enter-bootloader

If I run solo key verify it asks me to tap the button but no matter how many times I touch the button nothing happens and I get a timeout. One thing to note is that when I plug this key in no light comes on whereas on my backup the light always comes on. Below is the MacOS USB info on the key. This is my primary key and I'd like to get it working again without losing any secret data on it. Thanks in advance for any help.
