Smart power outlet - countdown timer error (ESP Exception)

Need Help With My Project
1

Hey i have a project to make a smart power outlet with countdown timer and alarm features. The alarm features is okay, buat the countdown timer sometimes got an error, i don’t know why. Maybe anyone can help me show which part is wrong, and tell me the better way to do it. Thanks!

My Blynk interface:

If youre using the Arduino IDE then you can install the ESP Exception Decoder tool:

You’ll then get an extra item in your Tools menu that allows you to paste your stack dump data in and it will give you some clues as to where the problem lies.
