Thermal run away

I received a thermal run away code. At first I thought the thermistor failed. But, I just recalled my micro SD card wouldn’t read so I reformatted it. It had a g-code on it for the micro Swiss ng extruder. I assume I need to get that g-code file back on the card. Please confirm

Which printer are you using?

Ender 3 max neo with a micro Swiss ng dual extruder upgrade
