Hello, yesterday I was doing some very basic software testing on the Teensy 4. I don't believe that I had it connected to anything other than USB. When I tried to run some code on it today it did not appear in the Arduino IDE or even in device manager. It also does not make the sound that normally plays when I connect a USB device to my computer. When I connect it to USB it begins to heat up, which indicates to me that it is running (the small square chip to the bottom left of the USB port heats up immediately, and the processor heats up more slowly).
I have swapped USB cables, I have tried it on a different computer, and I have no difficulty uploading code to my Teensy 2.0++. I have also rebooted. Does anyone have an idea of what might have happened and how to fix it? I wasn't working with hardware so I don't feel like I fried it with inappropriate voltage. Please let me know if you have any insight. Thank you.
