    Virtualbox - Segmentation fault (core dumped)

    I've been running Virtualbox without problems for many years on Ubuntu 16.04 before and now on 18.04.
    Since a few days I've been unable to start it. When I try, I see some black screens and then nothing more. When I try to run from command line I have a segmentation fault message.
    Here below I post the log file, where I can see some errors, but I'm unable to understand what really happens and how to possibly solve the problem:

    Code:

    Maybe try to reinstall guest additions?

    What version of VBox and VBox additions are you on? Did you do a recent update of packages that involve VBox? (Hint- Check your apt logs) Did the Host OS shutdown while the Guest VM was running?
