Matrix Portal M4 - No CIRCUITPY drive appears

Howdy folks,

I have a Matrix Portal M4 which has been working just fine up until today. After removing it from an older led matrix and then putting it on a new led matrix it no longer works. The neopixel on the back lights up when it is plugged in and if I double click the reset button I can get the MATRIXBOOT drive to appear. But when I hit the reset button once or pull the usb cable out and replace it no CIRCUITPY drive comes up. I've tried copying the Matrix Portal Circuitpython uf2 file back to the MATRIXBOOT drive. That will cause the Matrix Portal M4 to restart but still no CIRCUITPY drive.

So, what else can I try to see if I can get this Matrix Portal M4 back to life?

I have a quick update. I am able to copy the shipping demo from Adabox 16 to the MATRIXBOOT drive and that does work. However, if I then copy the circuit python uf2 file over I'm back to getting no CIRCUITPY.
