I recently got the QT Py ESP32-S2, and have been using Arduino IDE to upload sketches. Everything worked fine until I uploaded a WiFi example sketch that published a message to a public MQTT broker. This code ran fine but had an infinite loop situation. I tried uploading a previously functioning (non-WiFi) sketch, but it failed as the IDE could no longer find the board (i.e. could not select the Tools->Port). The board shows up on my laptop when I run lsusb, but does not show up under Disks unless it's in bootloader mode where it shows up as QTPYS2BOOT.
I tried resetting the board several times (per https://learn.adafruit.com/adafruit-qt- ... -3107941-7), and each time the same thing happens:
- press the reset button twice until it displays green, and drag the UF2 reset file to the QTPY2SBOOT
- board flashes yellow then briefly becomes purple
- rainbow swirl begins but gets stuck on "red" before restarting the swirl
- the board gets relatively hot
I took a short video of this to better illustrate what happens with the rainbow: https://youtu.be/5La7fhO8Oxk
Any ideas about what's wrong or how I can fix it?

What was the UF2 used here?- press the reset button twice until it displays green, and drag the UF2 reset file to the QTPY2SBOOT
This one?

Yes.
More specifically, this Github file: https://github.com/adafruit/Adafruit-QT ... -reset.UF2

How did you download the UF2 from Github?

By clicking 'Download'.
In my troubleshooting attempts, I also tried deleting that file and re-downloading it by clicking 'View raw' (which auto-downloaded the file). But it didn't make a difference.
