Can't open Settings, terminal commands hang

After reflashing the last time when a failed update made decrypting the disk on boot impossible, I have new issues. After I restored my old contacts, SMS and calls list manually (copied over the respective .db files in ~/.local/share from a backup), I could not open Settings any more. It acts like it’s opening but it doesn’t even show a window, just shows the desktop background, it’s not shown in the app list either. Sometimes it does open and show a window, then I click something and it freezes, I try to kill it in the app launcher but it doesn’t close.
Today after this happened I opened Terminal and ran “ip a” as I wanted to SSH in and investigate, but even “ip a” hung and didn’t show anything, and it didn’t die even after Ctrl-C. So I think something major is going on, like a big kernel issue or the eMMC failing or something. The problem is I couldn’t SSH in to look at the logs if there is anything there. For now I’m rebooting and if it happens again I’ll try to diagnose again.

It may help troubleshooting to open a terminal and start the application from the command line.

Likewise, it may help to clarify whether the problem can be reproduced immediately after reflashing or only after restoring files and potentially changing some settings etc.

What version did you reflash to? Stable byzantium? Something else?

I’ll try that. It was stable byzantium, yes.
I got the journal and boot.log from it for today. Weird that journalctl prints logs for March 18 and other dates after April 11, maybe there was weird stuff happening at one time with the system clock.

I launched gnome-control-center from terminal now and it works fine, so I don’t know. Maybe I’ll try again later.
