FNATIC React headset issue

Hello, I recently bought the Fnatic React headset, everything was fine until tonight when my microphone stopped working. I checked my sound settings, it is enabled and set as default, but the bar next to the mic doesn't move when sound is detected, and when I do tests to hear myself or whatever, nothing. At first, I wondered if it was a problem with the motherboard, but when I plug it into another computer, there is sound but the mic doesn't work either. I restarted my computer, checked if the drivers were updated, checked if everything was plugged in properly, and everything should be working normally. I don't understand. If you have a solution, I’m all ears. Thank you very much.
