VINS-Mono crashed

[ghost]

After making some code changes for OpenCV 4, I was able to build the workspace on Ubunto 18.0, ROS Melodic, OpenCV 4.0. However, when I ran the launch file

roslaunch vins_estimator euroc.launch It crashed:

How can I fix it?

I found it is because of this line:

cv::FileStorage fsSettings(config_file, cv::FileStorage::READ);

But I do not know why this could be a problem?

I have the same problem.How did you solve it Ubunto 18.04, ROS Melodic, OpenCV 4.5
