Romeo ESP32-S3 can't connect

I got a Romeo ESP-32S3 (SKU: DFR0994), and the motor code works fine. However, when it comes to the example webserver code, I can't get it to work.

I've installed the prerequistite libraries, changed the SSID and password to my network, and on the serial monitor it says

which to me, other than the core dump failure, seems to say it's operational, connected, and running. However, it doesn't show up in my router's list of connected devices and attempts at connecting or pinging it all time out. What am I doing wrong?
