COM ports stopped showing up

I have a nano and it has been working for the past couple of weeks. The wiring and the USB cable have not been changed. However, when I plugged it in today my COM ports are no longer showing up and there is nothing showing up in the device manager settings either. Does anyone have any ideas on what could be going wrong?

Is it the classic ATmega328P-based Nano, or one of the new variants (Nano 33 IoT, Nano 33 BLE, Nano RP2040 Connect)?
