Description:
Opera GX crashes immediately on startup with Signal 11 (SEGV) before any window appears. The crash is 100% reproducible and always occurs at the same offset (opera + 0x9780767). This is a fresh install with no prior configuration.
Comparison with other browsers on same system:
Opera Stable 129.0.5823.22: works perfectly
Brave 1.88.136 (Chromium 146): works perfectly
Opera GX 128.0.5807.97: SEGV on startup
All three are Chromium-based. Only Opera GX crashes. This confirms the issue is 100% Opera GX-specific, not related to GPU drivers, Mesa, kernel, Wayland, or system libraries.
Tested workarounds (all crash identically at the same offset):
opera-gx (default, Wayland)
opera-gx --ozone-platform=x11
opera-gx --no-sandbox
opera-gx --disable-gpu
opera-gx --no-sandbox --ozone-platform=x11
opera-gx --disable-gpu --ozone-platform=x11

Notes:
Crash offset 0x9780767 is identical across all attempts, regardless of flags or display server
Crash occurs during early initialization, before any UI renders
Opera Stable works fine on the exact same system, proving this is not a driver/system issue
The crash may be related to GX-specific initialization code (gaming features, GX Control, etc.)
