RadioLib: Problems with LoRaWAN using SX1262 on Helium Network

Describe the bug After successful OTAA, restarting results in the microcontroller producing -12 (Invalid frequency) error codes. After enabling debug mode I can see that it tries to set the frequency to 0MHz [LoRaWAN] Sending uplink packet ... Channel frequency UL = 0.000000 MHz

To Reproduce

#include <RadioLib.h>
SX1262 radio = new Module(2, 5, 22, 4);
LoRaWANNode node(&radio, &EU868);

void setup() {
  Serial.begin(115200);

  Serial.print(F("[SX1262] Initializing ... "));
  int state = radio.begin();
  if(state == RADIOLIB_ERR_NONE) {
    Serial.println(F("success!"));
  } else {
    Serial.print(F("failed, code "));
    Serial.println(state);
    while(true);
  }

  uint64_t joinEUI = 0x111111111111111;
  uint64_t devEUI = 0x111111111111111;

  uint8_t nwkKey[] = { 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11};
  uint8_t appKey[] = { 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11, 0x11};

  Serial.print(F("[LoRaWAN] Attempting over-the-air activation ... "));
  state = node.beginOTAA(joinEUI, devEUI, nwkKey, appKey);
  if(state == RADIOLIB_ERR_NONE) {
    Serial.println(F("success!"));
  } else {
    Serial.print(F("failed, code "));
    Serial.println(state);
    while(true);
  }
}

void loop() {
  Serial.print(F("[LoRaWAN] Sending uplink packet ... "));
  int state = node.uplink("test", 10);
  if(state == RADIOLIB_ERR_NONE) {
    Serial.println(F("success!"));
  } else {
    Serial.print(F("failed, code "));
    Serial.println(state);
  }

  while (true);
}

Expected behavior After reboot, the microcontroller should retrieve all of the data from EEPROM and use all of the usable channels, in this case 8 channels, just like on TTN.
