Ubuntu 22.04 black screen after bootup following some package upgrades

I updated the following packages via the CLI (from another device) and now after Ubuntu has booted, I am just presented with a black screen...

apparmor/jammy-updates 3.0.4-2ubuntu2.2 amd64 [upgradable from: 3.0.4-2ubuntu2.1]
gnome-remote-desktop/jammy-updates 42.7-0ubuntu1 amd64 [upgradable from: 42.0-4ubuntu1]
grub-efi-amd64-bin/jammy-updates 2.06-2ubuntu14.1 amd64 [upgradable from: 2.06-2ubuntu10]
grub-efi-amd64-signed/jammy-updates 1.187.3~22.04.1+2.06-2ubuntu14.1 amd64 [upgradable from: 1.182~22.04.1+2.06-2ubuntu10]
libapparmor1/jammy-updates 3.0.4-2ubuntu2.2 amd64 [upgradable from: 3.0.4-2ubuntu2.1]
shim-signed/jammy-updates 1.51.3+15.7-0ubuntu1 amd64 [upgradable from: 1.51+15.4-0ubuntu9]

The problem is, I'm not sure which of these caused the problem and I can't find anything that jumps out in any log files. Presumably it is something to do with the gnome-remote-desktop but I'm unsure for certain.

Does anyone know what I could do to figure out what has broken so that I can determine how to fix this please?

If it's of any relevance, my VNC connection has also stopped working and now just times out - which is of no surprise if the GUI isn't working I guess.

Edit

I rolled back the gnome-remote-desktop package and rebooted but that made no difference. I am trying to do the same with each one but it won't let me roll back the grub packages due to dependency problems with shim-signed which also won't roll back (see below):

On boot up try an older kernel.

@David I don't have any other kernels available to select.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
