It sounds like the Create 3 stops publishing data at this point. It supplies the odom->base_link transform which you need in order to see the robot on the map, and to get the left/right wheel transforms.
Are you using simple discovery or the discovery server? Also could you share the Create 3 logs from the webserver after this issue occurs?
@roni-kreinin I'm using the Discovery Server. I only have 1 robot
Also, the RPi address changed, so I did the Discovery Server setup again, and it's running longer than I expected
Although here you can see I'm still getting that LidarScan error. That topic number keeps increasing btw.
Here are the Create3 logs. It keeps saying the wifi is disconnected, but I assume that's because of the discovery server
@rohanchandra-cpe @roni-kreinin I run through the same set of problems but without using a discovery server. I will update once I have figured out the problem.

Even though I do not use discovery server, I face this issue too.

With this configuration, the TurtleBot 4 is able to fully function without the Create® 3 being connected to Wi-Fi.(refer)
@roni-kreinin The LaserScan message received number keeps increasing and throws error in rivz. I did not use discovery server in my case.
This is the logs from the create3 base.
This issue is being closed due to inactivity. If you are still experiencing the issue, feel free to reopen this ticket when you are ready to continue the troubleshooting process.
Please provide the following information:
Package version: "sudo apt install ros-humble-desktop" is how I installed ROS2
Expected behaviour I should be able to run SLAM and Rviz until I decide to quit. I should also be able to drive the robot for as long as I want and save a copy of the generated map in Rviz.
Actual behaviour When following this tutorial: https://turtlebot.github.io/turtlebot4-user-manual/tutorials/generate_map.html, Rviz, SLAM, and the teleop_twist_keyboard run for some time, but then all fail. The teleop_twist_keyboard freezes (unable to CTRL+C out of it), errors appear in the simulator, and my robot in Rviz becomes an unmovable block dot.
