I did an autoupdate from 6.4.5 to 6.5.3 and after a reboot, save and another reboot I get this.
At the same time my Vivaldi browser informed me there's something wrong with the profile file and I've lost all my Vivaldi's tabs and settings. Are there related? Can they be caused by the Easy update? The system itself seems to be working fine, Firefox hasn't lost any tabs nor settings. I haven't checked anything else.
System start
System shutdown (with save)
