I tried to run the following steps in the order shown below, but I get an error and it stops halfway through. Can I ask for an advice for their cause and a solution?

-Execution steps: Terminal1: roslaunch dvs_tracking flyingroom.launch auto_trigger:=true Terminal2: rosbag play -r 0.7 evo_flyingroom.bag

-Error messages: ================================================================================REQUIRED process [dvs_tracking-7] has died! process has died [pid 4064, exit code -8, cmd /home/user/catkin_ws/devel/lib/dvs_tracking/dvs_tracking_ros events:=/dvs/events remote_key:=/evo/remote_key pointcloud:=dvs_mapping/pointcloud __name:=dvs_tracking __log:=/home/user/.ros/log/c87c824e-e92c-11eb-a2a5-080027ad98cd/dvs_tracking-7.log]. log file: /home/user/.ros/log/c87c824e-e92c-11eb-a2a5-080027ad98cd/dvs_tracking-7*.log Initiating shutdown!
