realsense-ros: [ROS2] Realsense Camera Node Error

I receive the following error while executing:

ros2 run realsense2_camera realsense2_camera_node

on my SBC Debix Model A (2GB RAM) with Ubuntu 22.04 LTS (Kernel: 5.15.71) and ROS2 Humble Hawksbill installed on it.

I’ve installed “succesfully” (no problems appeared) both the SDK and RealSense libs (and dependencies).

The camera is correctly plugged via USB, as it shows the lsusb command:

Bus 002 Device 003: ID 8086:0b3a Intel Corp. Intel(R) RealSense(TM) Depth Camera 435i

3.22 is newer than 3.8, so it should be fine.
