Using NFC read and I2S audio output together causing issues in ESP32. Using them separately works fine. Libs: ESP32-audioI2S & Adafruit PN532

Question

• The wifi client returns no data when I add in print statements on the library.
• The issue happens right after I add this line to the loop. success = nfc.readPassiveTargetID(PN532_MIFARE_ISO14443A, uid, &uidLength);
• I am not sure if its a memory issue either, I can see quite a bit of heap memory left on the logs.
