Arduino nano 33 not working with blynk

Arduino nano not working with blynk showing error.
i used arduino mkr 1010 example as shown in arduino official website.
error u can see in attached pic.

you have Nano 33 BLE selected, not Nano 33 IoT. in case of successful upload you would delete the bootloader of your 33 IoT so be carefull

when i start uploading code. the board is automatically disconnecting
