No worries mate, already found the solution. the json files located somewhere else and after deleted them, I managed to update it.

Hi, I’m managed to update the board manager as a requirement for module 7(MQTT), but as soon as it success, an error keep repeating itself for every uploaded code to my ESP32 as shown below:

I tried to reinstall my Arduino IDE, but the error still there when I ran any code. Hope you can help me, thank you.

Hi.
I’m sorry for taking so long to get back to you.
The error is documented here: https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/fatal-errors.html#integerdividebyzero
However, I don’t know why it is happening. What is the code that you are running? Which project are you following?
Regards,
Sara

Hi Sara, thank you for your suggestion. I found that the error came out when there is Adafruit SSD1306 library in my code. Therefore, I changed all my display library to U8x8 library and my code has worked again like before. 

I’m glad you were able to find out and fix the problem.
I’ll mark this question as resolved.
Thank you for your interest in our content.
Regards,
Sara
