to /etc/apparmor.d/abstractions/lightdm_chromium-browser did not help (I tried that in case it was a matter of yet more filename changes on google's packaging).
google-chrome --no-sandbox works around the issue, with obvious usability (manual startup or manual configuration of switch), stability and security drawbacks.

/opt/
to /etc/apparmor. d/abstractions/ lightdm_ chromium- browser did not help (I tried that in case it was a matter of yet more filename changes on google's packaging).
