Help! Wio Tracker board can't be programmed.

I got my “Wio Tracker” board connect to Arduino IDE and worked fine. Until I burned a sample named “GSM_full_function_mode”. Then I saw “MCU Stanby…” in the serial monitor and the board can’t be burned anymore (The error message is “No device found on COM10. An error occurred while uploading the sketch”).

How to recover my board? It’s urgent.
