I also have this problem when hitting a breakpoint in Unreal 5.1 from JetBrains Rider 2022.3.1 while in vanilla Ubuntu 22.04. When the window shows it actually makes the mouse pointer disappear and I have to rely on the keyboard to "Force Quit" to get the pointer back.
With that being said, I have to agree with Daniel van Vugt on comment #4, the status on Unreal PID does change from "S" to "t" when the breakpoint is hit.

The "Disable Force Quit or Wait" gnome-shell extension does work and solves the problem: https:/ /extensions. gnome.org/ extension/ 2257/disable- force-quit- or-wait- button/
