I too would ask you to start over, by uninstalling and killing all chromium processes.
An operational note, you really shouldn't be logging in as the system account. You log in as yourself, and if you need to do system things, become root temporarily.
Also, logging out will kill any processes started by you which haven't been placed in the background.
For install:
sudo /bin/bash
exec su - root
pgrep -l chromium # ensure list is empty, otherwise kill those processes
# pkill chromium
apt install chromium-browser
exit
id # confirm you are now yourself and not root
# start chrome with specific directory
chromium-browser --user-data=~/.config/chromium >/dev/null 2>&1 &
# you could make this an alias in your .bashrc:
# alias chrome='chromium-browser --user-data=~/.config/chromium >/dev/null 2>&1 &'
You could add nohup
to keep it running after logout, but re-attaching to it after logging in is problematic.
Once chrome is started, edit settings:
Choose Continue where you left off
Choose Offer to save your web passwords (in advanced settings)

Very easy, you must go to Security settings, then you just change your password and this will log all computers out of anything to do with your Google chrome account and it also stops that computer logging back in if the password was saved on that computer, until you get back to that computer station again.
