I recently bought the NodeMCU ESP8266 to work on an embedded project, and for whatever reason, the board will only allow me to upload Arduino sketches when I unplug and replug in the board via the Micro-USB cable. I don't have any jumper wires connected to pins in the board--just the Micro-USB cable. The IDE gives me the following:

Like I said, it programs fine when I unplug and replug in the board, but it is quite a nuisance to do this every time. I'd like the board to automatically start running my code after uploading. Here's what I've tried/found:
-I've made sure the baud rates are matching in the device manager and the upload speed tab in the IDE.
-The device is in fact being picked up in the device manager with the correct driver: USB-SERIAL CH340.
-I've tried pressing the flash button before programming.
-I've tried connecting the ground pin on the NodeMCU to GPIO pin 0.
-Tried reinstalling drivers.
-Tried switching boards.
This may also explain why my serial monitor is so inconsistent as well; sometimes it outputs nothing and sometimes it outputs garbage, but that's a separate issue that I won't worry about for now. Can someone please help me out here? I've referenced a lot of other posts on here as well as tutorials but none have helped me thus far.
Thanks
