[Critical Bug] Cursor AppImage Crashes on Ubuntu 24.04 (Error 132, Electron Sandbox Issue)

Describe the Bug

Cursor crashes immediately on Ubuntu 24.04 when launching the AppImage (Cursor-1.1.5-x86_64.AppImage). Error code: 132. The crash appears to be caused by Electron’s sandbox failing due to incompatible namespace restrictions in Ubuntu 24.04.

Steps to Reproduce

Download the latest AppImage (v1.1.5) from the official Cursor website

Run it on a clean Ubuntu 24.04.2 LTS system using terminal

Command used:
./Cursor-1.1.5-x86_64.AppImage --verbose
The app crashes immediately with the following fatal error:
Failed to move to new namespace: errno = Operation not permitted
FATAL:zygote_host_impl_linux.cc(207)] Check failed: .
Trace/breakpoint trap (core dumped)

Expected Behavior

Cursor should launch normally and show the main editor interface.
The AppImage should detect unsupported sandbox environments and automatically disable it or provide a fallback option.
