teensy 3.6 does not work anymore

I just had my teensy 3.6 connected to my pc (led was on), but was not found by the arduino ide like normal. So I reconnected it and now suddenly not even the led is on anymore (my old program does not run aymore) and it’s still not found by the IDE. What could be the problem and how can I fix this?


In that link please look this section named, Teensy not recognized by teensy loader.

And try to upload the program manually, by pressing the button on the board after you follow the steps.

Followed the steps but nothing happened

Try to reset it. And update the drivers if possible, it should work.
