Please see the earlier posting

Serial1.begin in class constructor hangs core

I’ve commented out everything in main loop and setup and it still fails. Serial1 micht be the issue, as it is initialized in Garan library class constructor. This need fixing.

As per this post, Serial1.begin() before calling setup() caused issues.. Please see the specific link:

Serial1.begin in class constructor hangs core

Workaround: Move Serial1.begin() from constructor to void setup() {}

If you move the initialization that happens in the constructor

SeeedRFID RFID(RFID_RX_PIN, RFID_TX_PIN);

to the setup(), this may work.The constructor function may need to be duplicated as an init() method and called in setup()
