ORB_SLAM3 Points and frames initialized quickly (ROS command)

Hi, I tried to run ORB SLAM3 with using ROS. When I run ORB SLAM3 with this command to use Mono-inertial version "rosrun ORB_SLAM3 Mono_Inertial ~/ORB_SLAM3/Vocabulary/ORBvoc.txt ~/ORB_SLAM3/Examples/Monocular-Inertial/RealSense_D435i.yaml /camera/image_raw:=/camera/color/image_raw /imu:=/camera/imu", Screens, points, and frames appear, but points and frames are quickly initialized and disappear. It's happening and disappearing repeatedly. Below is an error message that appears in the terminal window when the command is entered. Can I know the reason and solution for this error?
