Guru meditation error

[rautmithil]

I am trying to connect to a university's Wi-Fi network which uses TKIP, PEAP version 0 for phase1 and MSCHAPV2 for phase 2. No certificates are required.
I am using this example with Adafruit ESP32 Huzzah with the modified line

esp_wpa2_config_t config = WPA2_CONFIG_INIT_DEFAULT();
esp_wifi_sta_wpa2_ent_enable(&config);

One in 10 times, it gets stuck in the connect loop

while (WiFi.status() != WL_CONNECTED) {
        delay(500);
        Serial.print(".");
 }

On other occasion it throws

Guru meditation error of type LoadProhibited occurred on core 1. Exception was unhandled.

as soon as it enters the connect loop. Any leads what could be the problem. Stack traceback reveals this but I am finding it difficult to make sense out of it.
