I have a teensy 4.0 that I started uploading example codes to. I was having issues receiving serial communication so I kept trying different example codes. Then I noticed that it did not show as a teensy device in windows device manager. Now I cannot enter manual program mode or see the teensy on Arduino IDE.

I have tried a different computer that did not see teensy 4.0 at all.
I have ~3.3V output from teensy
I have 4.98V from power regulator to Vin
I tried holding the reset button for 15 seconds but the Teensy only flashes red once
Currently windows sees it as SE BLANK RT Family
