I’m new to Ubuntu and recently installed Ubuntu 24.04 LTS. A few times, when an app freezes and I choose “Force Quit,” my screen goes blank and I’m taken back to the login screen. Is this normal behavior? How can I prevent it, or safely recover when an app stops responding?
Normal behavior it is not but surely it has a cause.
Please inform your hardware specifications and we go from there.
It’s not normal, no.
Is it always the same app that does this? If so, which app? Or, do you find it with different apps?
Please open a terminal, type the word inxi and press Enter. Post the results here.
To copy the results from a terminal, highlight the results with your mouse; right-click; select Copy. Then you can paste here.

On Ubuntu 24.04 you need to install inxi first.
sudo apt update && sudo apt install inxi
Once installed, to give us complete system information use this command:
inxi -Fzxxx

This sounds like something is causing the entire user session (or even gdm) to crash
