I have the same issue here with an M5Stamp-PICO (ESP32-PICO-D4) running the Basic example.
I got the setup page the first time and entered my settings and rebooted.
The device does connect to the access point but does not get an IP address and the serial monitor reports 255.255.255.255.
I have looked at the library and tried to force some static settings (ip, gateway, netmask), replacing the call WiFi.config( INADDR_NONE, INADDR_NONE, INADDR_NONE ); but that did not work at all.
My Arduino expertise is quite limited, so I stopped there.
Interestingly, now that the settings are in Flash, the Advanced example does connect and does get an IP address.
Also as a bonus, the router properly identifies the device as esp32-C30B00 (it did not when running the basic example)

I have the same issue with TTGO T-Display board.
Surprisingly, when I compile the same sketch on MacOS with the same library version it works

I was also having this problem with nodemcu esp32 which is also described here #9

Commenting this line fixed it for me https://github.com/Juerd/ESP-WiFiSettings/blob/master/WiFiSettings.cpp#L469

Which is a workaround mentioned here espressif/arduino-esp32#2537 (comment) but it is not longer working because it was fixed here espressif/arduino-esp32@ad4cf14

This means the library needs some logic to detect which version of the platform is running to apply the workaround or not.

As @Juerd indicated in other issues he is not longer working on the library (understandable) so I downloaded it and patched it for my project which makes it work well.
