[Bug] Crashpad handler repeatedly crashes with SIGBUS on Linux AppImage

Environment

• Hydra version: 4.1.3
• Electron version: 40.9.3
• OS: Omarchy / Arch Linux
• Installation: AppImage
• Desktop: Hyprland/Wayland

Problem

Hydra’s bundled chrome_crashpad_handler repeatedly crashes with SIGBUS during shutdown.

The crash occurred four times on the same day:

• 19:40:39
• 22:20:46
• 22:36:35
• 22:41:30

Each crash had:

• Signal: SIGBUS
• Code: BUS_ADRERR
• Identical Crashpad binary offsets
• The temporary Hydra AppImage mount was unmounted immediately before the crash

Representative stack:

chrome_crashpad_handler + 0x63490
chrome_crashpad_handler + 0x75785
chrome_crashpad_handler + 0x41ec7
libc.so.6
__libc_start_main
chrome_crashpad_handler + 0x374ca

The main Hydra/Chromium process appears to exit normally. Only the Crashpad handler crashes. No OOM, filesystem, NVMe, or Btrfs errors were present.

Expected behavior

Hydra and its Crashpad handler should shut down without crashing when the AppImage mount is removed.

Additional information

The Crashpad database is located at:

~/.config/hydralauncher/Crashpad

The crash is reproducible across multiple Hydra launches. No user data loss was observed.
