ESP32 crashing when using I2c OLED display and external interrupts

Hello !
Newcomer on RNT but old on electronics… I never used the ESP32 before and just bought your ESP32 course.

I have a persistent and intriguing problem here with a very simple ESP32 project.

Basically, I’m using a button to trigger an external interrupt on gpio5 and it works exactly as it shoud do, except when I put a SSD1327 OLED i2c display together. Every single time when I press the button, the esp32 crashes and reboot.
The display works as expected if I don’t press the button.
Do you have any insights of what’s going wrong ?
Thank you

Antonio

P.S.  I’m using the U8G2 display library

Solved ! The ESP32 board was defective, I changed it for a new one and everything worked.
