App PureOS Store crashes after OS update

After the today (November 17) OS update for Byzantium, done via the PureOS Store app, the app itself crashes on startup short after writing Software catalog is being downloaded. In /var/log/syslog it shows the following error messages:

I can ssh into the device and start gnome-software fine from the shell, and it seems to work fine from there:

ssh purism@192.168.178.48

purism@pureos:~$ gnome-software

But, when I do the same in the terminal app of the L5, it crashes also.
