So this indicates a power or RF interference problem.
For power, check again that the USB port can supply sufficient current. If you have a USB3 port, try that one. USB plugs may be worn. And cables are a common problem.
For RF interference, try the suggestion of HF blocking of the EN pin: add a capacitor between EN and GND (>100nF) and a pull up resistor between EN and 3.3V of 4.7 kOhm.
