Hey everyone. So I was just experimenting with a ESP8266 as im pretty novice when it comes to blynk and arduino. I ended up using the start up template to display live readings of a potentiometer as well as have a button on the blynk app to turn on and off a LED.
I tried adding another LED to the board and another switch in blynk and the board crashed and now im getting the following error.

I made no changes to the code from when it was working 100% as intended and now I it just connects to wifi and succefully connects to blink then resets. I’ve tried reuploading, reseting, unplugging everything. Not sure what to do from here. My full code is below. Thanks in advance!
