ESP32 U8GLIB_SH1106_128X64 Unhandled Exception please help! #26

Hi, I am working on a school project with an ESP32, I managed to get my OLED: https://ibb.co/yyRmHMz To work well using U8GLIB_SH1106_128X64 u8g(13, 12, 5, 9, 11); on an Arduino Uno, however it will not run on an ESP32, here is the error:

Raw error:

I adjusted the pin outs in the U8GLIB_SH1106_128X64 u8g(x, x, x, x, x); code to ensure it works with ESP32 pin out. I also tried uploading code to the ESP32 with nothing except the line just mentioned, and it still generated the error.

Thanks in advanced for your help, I really want to use your library because Adafruit is to difficult for me to understand. I appreciate your help!
