Irremote Teensy 3.2, enableIRIn() not working

[ppeerr]

Hello!

I'm trying to get the irremote code (see code below) to run on a Teensy 3.2 but having some issues with the following line:

IrReceiver.enableIRIn(); // Start the receiver

the code hangs and won't continue to run. The Serial.println() on the line before writes a string to the serial monitor.

Any ideas of what might be wrong?

HW: Teensy 3.2
Arduino: 1.8.13
Teensyduino: 1.53
