Reboot into recovery. Hold Left Shift at boot, select "Other options" then pick the latest recovery mode.

Pick "root shell prompt" when the recovery menu loads.

Run the following:

mount -o remount,rw /

chown -R root: /etc/sudoers{,.d}

chmod -R 440 /etc/sudoers{,.d}

chmod 755 /etc/sudoers.d 

reboot
