I know this question is similar to may other ones but none of them seem to solve my problem.

What can be wrong?
How to solve?
Any ideas?
Thanks.
According to your comment:
I downgraded from opencv-devel-4.2.0-4.1.x86_64 to opencv3-3.4.9-2.4.x86_64 and it is not crashing anymore..
I can only conclude the package is broken.
In case you really need OpenCV 4, I suggest you to build from sources.
