I have the same problem before. My operation system version is Ubuntu 18.04, ROS2 version is eloquent, device platform is Nvidia jetson nano(4GB mermory).
After I try some commads, the A2M12 does work very well, and I can see data with rviz2 tool.

First of all, I check USB ports. Use lsusb command to find out which USB port is my A2.
lsusb result as follows:

jetson@Nano:~$ lsusb
Bus 002 Device 004: ID 8086:0ad4 Intel Corp.
Bus 002 Device 003: ID 05e3:0626 Genesys Logic, Inc.
Bus 002 Device 002: ID 2109:0817 VIA Labs, Inc.
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 8087:0a2b Intel Corp.
Bus 001 Device 010: ID 10c4:ea60 Cygnal Integrated Products, Inc. CP210x UART Bridge / myAVR mySmartUSB light
Bus 001 Device 006: ID 24ae:2013
Bus 001 Device 005: ID 25a7:fa70
Bus 001 Device 004: ID 05e3:0610 Genesys Logic, Inc. 4-port hub
Bus 001 Device 002: ID 2109:2817 VIA Labs, Inc.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

So, /dev/bus/usb/001/010 is my RPLiDAR A2. Then run this commands:
sudo chmod 777 /dev/bus/usb/001/010

And then, check /dev/ttyUSB0 is my RPLiDAR or not. In my device, it is.
run: sudo chmod 777 /dev/ttyUSB0

Secondly, try to run sllidar_node by correct baud rate, and my the correct baud rate of A2M12 is 256000.
So, I run node successfully by command: ros2 launch sllidar_ros2 view_sllidar_launch.py serial_baudrate:=256000

However, it can work in virtual machine, and doesn't work in Nano, I find the problem is power supply of usb.
Because the virtual machine is on my PC with 5V1.3A, and Nano is 5V?A ( I don't know).
Finally, I pull out the HDMI in Nano, then it does work well in Nano.

I met the same problem here, the sllidar_node is working when I use ros2 launch sllidar_ros2 view_sllidar_launch.py command. But when I use ros2 run sllidar_ros2 sllidar_node to run the single node, the same error come out：

ros2 run sllidar_ros2 sllidar_node 
[INFO] [1685514051.594998751] [sllidar_node]: SLLidar running on ROS2 package SLLidar.ROS2 SDK Version:1.0.1, SLLIDAR SDK Version:2.0.0
