So I can't replicate this accurately with my MagTag, but I did experience something similar yesterday.
Here's how I fixed it:
1) Enter ROM bootloader mode, https://learn.adafruit.com/adafruit-mag ... -3076820-1
2) Download the bootloader for MagTag, https://learn.adafruit.com/adafruit-mag ... -3077972-6
3) Used the Web Serial ESPTool to erase the magtag, then upload the new tinyusb bootloader binary, https://learn.adafruit.com/adafruit-mag ... al-esptool
4) Restarted the MagTag and dragged a new WipperSnapper UF2 onto the BOOT volume.
I'm not yet sure where/how it's getting stuck in the bootloader.

Do you see the WIPPER drive mounted on your computer? Or any boot drive?

On a win10 box, it does pop up long enough to show a "wipper" disk with a secrets.json and wipper_boot_out.txt
I was able to double click the txt file before the loop only once, but the file was blank.

SandPig + Scottlnrd - I spent today working on this issue. Attached is a new version of WipperSnapper for the MagTag. Please let me know if it has the same issue, or creates new issues.

First, you work too late. I hope you love what you do. I just wrapped a 16hr day and there is zero love there! (totally my fault)
Second, it worked! MagTag is online and button presses (seemed like a good test) are working as expected. You rock!
The neopixels do flash green every few minutes, but it doesn't seem to be an issue so I'll assume that's a positive feedback thing.
I'll report any oddities that I come across.

This is to be expected, that's a status indicator letting you know the hardware is still connected to IO.
NOTE: Beta.4 has been released and includes the fix for the magtag bootloop.
