It just happened to also arise in some cases with Kernel updates but this is
just the last instance of it happening.
The black screen with blinking cursor happened to me many times in the past
when during a fresh install not installing proprietary drivers and later on
installing nVidia drivers downloaded from nVidia.
You can search the internet for 'black screen', 'ubuntu', 'blinking cursor',
'nVidia'... and will find plenty of issues reported but none of the solutions
ever worked for me.
The point is that I previously never knew how to handle this situation and
resorted to a fresh install as I though my system was definitely broken.
This is until I realized that it is still possible to access the system with
some keyboard commands as explained above in order to start up Ubuntu and to
restore its proper startup behaviour by subsequently updating the driver to the
proprietary tested version, which was by the way only the last step in solving
the black screen issue.
The other bug report only provides the code to restore the drivers but not what
to do when the system is hanging with the black screen.

Title:
Boot issue with Ubuntu 22.10 Kinetic Kudu since Kernel 5.19.0.15.15,
now hanging with blinking cursor after update to Kernel 5.19.0.21.21
Status in linux package in Ubuntu:
Confirmed
Bug description:
When starting the PC, the splash screen freezes with the motherboard logo
displayed.
As my disk is encrypted the decryption field does not appear below the logo.
By typing [ALT] + [CTRL] + [DEL] then the splash screen appears again
followed by a start-up menu with the following line:
*Ubuntu
Advanced options for Ubuntu
By selecting 'Advanced options for Ubuntu' the following submenu appears:
*Ubuntu, with Linux5.19.0-15-generic
Ubuntu, with Linux5.19.0-15-generic (recovery mode)
Selecting the second option, then the system starts loading with the initial
lines of code:
Loading Linux 5.19.0-15-generic ...
Loading initial ramdisk ...
When code has finished loading, the last line at the bottom of the screen is
for unlocking the disk:
Begin: Mounting root fie system ... Begin Running /script/local-top ...
Please unlock disk nvme0n1p3_crypt:
Then i type in the code and hit [return] and more code is loading, until a
recovery menu with purple background appears, with the title:
Recovery Menu (filesystem state: read-only).
I select the first menu item:
resume Resume normal boot
and hit [return].
The menu changes to the notification:
You are now going to exit the recovery mode bla bla bla
with the [OK] button below it.
I hit the [OK] button and then the login screen finally appears.
I will post a video of the complete boot sequence later on as I need
to install a softaware to edit the video.
It is noteworthy that on my previous Ubuntu 22.04 install the same
issue with the frozen splash screen occurred when my system was
updated with Kernel 5.15.5, but then I did not try out to execute the
[ALT] + [CTRL] + [DEL] command.
Therefore the bug is probably affecting all kernels from 5.15.5
upwards.
