Very much an Arduino newbie here, so hoping this is a simple fix. Anyways, I'm trying to get a lidar sensor working, and I am using a helloworld sketch off of github. GitHub - stm32duino/VL53L4CX: Arduino library to support the VL53L4CX Time-of-Flight high accuracy ranging sensor with multi target detection
The code compiles and verifies successfully and without any warnings (I have all warnings at 'all'), and it is supposed to start running the sensor, but the Serial Monitor never even opens up, and it doesn't appear any of the code is executing. I've tried adding print statements all around the code to see what's running and what's not, and still nothing.
I'm not 100% sure the way my sensor is wired is compatible with the code. I'm using an Adafruit Qt Py with SAMD21, and the code appears to be written primarily for the STM32 Nucleo board. Either way, shouldn't print statements still work even if the sensor isn't wired correctly? I'm just surprised I'm getting no output, error or otherwise.
Any feedback is much appreciated, thanks!

* To use this sketch you need to connect the VL53L4CD satellite sensor directly to the Nucleo board with wires in this way:
* pin 1 (GND) of the VL53L4CD satellite connected to GND of the Nucleo board
* pin 2 (VDD) of the VL53L4CD satellite connected to 3V3 pin of the Nucleo board
* pin 3 (SCL) of the VL53L4CD satellite connected to pin D15 (SCL) of the Nucleo board
* pin 4 (SDA) of the VL53L4CD satellite connected to pin D14 (SDA) of the Nucleo board
* pin 5 (GPIO1) of the VL53L4CD satellite connected to pin A2 of the Nucleo board
* pin 6 (XSHUT) of the VL53L4CD satellite connected to pin A1 of the Nucleo board
