When I reboot, the issue is the same as on the previous occasion - Only a black screen shows up with a blinking cursor, no login screen. Solution posted in the linked issue works for this issue too - Choose Advanced Options in GRUB and boot with an older kernel version (4.13.0-45 for me). I proceeded to remove the new kernel version until the issue is fixed.
