MR24HPC1 connected to XIAO ESP32S3 Sense fails to print data to serial terminal

I am trying to run the MR24HPB1_Example.ino example.

This is the output :

16:15:52.549 -> ESP-ROM:esp32s3-20210327
16:15:52.549 -> Build:Mar 27 2021

16:15:52.549 -> entry 0x403c98bc
16:15:52.643 -> Readly

Looks like it is hanging, is this code compatible with the MR24HPC1?

Any thoughts?
Thank you

It may be happening because in the setup() code when we call:

radar.SerialInit();

Serial1 (which is internally connected to the flash memory in some dev boards) is used for communication between the microcontroller and the radar. This leads to a collision, and the MCU crashes and continuously tries to reset, showing you that error message.
Do you know of any workaround to change this to other serial pins, or have you found a solution to this problem?
