Thank you for taking the time to report this bug and helping to make
Ubuntu better. It sounds like some part of the system has crashed. To
help us find the cause of the crash please follow these steps:
1. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
2. If step 1 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.
Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.

Title:
gnome-magnifier prevents starting a graphical session
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
After upgrading from Ubuntu 22.10 to Ubuntu 23.04, I am unable to
login to my session as I always get the "Oh no! Something has gone
wrong." error message.
I have screen magnifier enabled, but disabling it using:
gsettings set org.gnome.desktop.a11y.applications screen-magnifier-enabled
false
makes the issue disappear. I can reproduce the bug inside a virtual machine
on Windows as well, with different hardware.
The only piece of log I can find and that might be linked to the issue is:
