After flashing the image, edit /boot/cmdline.txt and remove the first part "console=serial0,115200 "
console=serial0,115200 console=tty1 root=PARTUUID=567d5380-02 rootfstype=ext4 fsck.repair=yes rootwait sysrq=0
Replace with:
console=tty1 root=PARTUUID=567d5380-02 rootfstype=ext4 fsck.repair=yes rootwait
It will then boot fine.
