I have a Gentoo 13 system built from sources following the handbook. Its in the default/linux/amd64/13.0 configuration. I use the system to test other software on the platform. Software testing is the only reason this VM exists.
$ eselect profile list
Available profile symlink targets:
[1] default/linux/amd64/13.0 *
[2] default/linux/amd64/13.0/selinux

Naively, I tried to set the profile to GNOME. I did not realize its basically incompatible with Gentoo (why is it even a choice?) and now the package manager is mostly broken. I set the profile back to what I used during the installation but it did not fix the problems introduced when attempting to use the GNOME profile.
emerge spews lots of messages (shown below), but I'm not sure what's wrong or how to fix it. I keep looping back to emerge --update --newuse --deep @world because emerge repeatedly tells me to run it, but it does not appear to fix anything since the same problems are continually reported.
How can I determine what is causing the problems, and how can I fix it?
I realize "How to fix what emerge is complaining about?" is a crummy title. But I have no idea what is wrong, so I don't know what to say the problem is or ask how to fix it.
Related, here are some resources that have not been helpful in fixing the problems with emerge. I'm not even sure if the blocked packages are the problem or a symptom of the problem.
# emerge --update --newuse --deep @world
