System Information:

• Update stream: Early Access
• Core version: 121.0.5600.55
• Operating system: Windows 11 64-bit
• Chromium version: 137.0.7151.122

Issue Description:
Opera GX consistently crashes and automatically restarts when typing the letter “B” into the address bar. The crash occurs as soon as the autocomplete drop-down appears. This behavior is reproducible and occurs both in normal and incognito modes.

Steps to Reproduce:

• Launch Opera GX.
• Click on the address bar.
• Type the letter “B”.
• The autocomplete drop-down briefly appears.
• The browser crashes and restarts automatically.

Expected Behavior:
Autocomplete suggestions should appear without causing the browser to crash.
Actual Behavior:
Typing “B” triggers a crash and automatic restart of the browser.

Troubleshooting Performed:

• Disabled all extensions and mods.
• Cleared browsing data, cache, and history.
• Deleted History and Visited Links files from the profile directory.
• Tested in incognito mode (issue persists).
• Disabled hardware acceleration via settings and launch parameters (--disable-gpu).
• Ran full malware scan using AVG (paid version) and system diagnostics via Advanced System Care.
• Verified issue persists even when browser is launched offline (suggesting local rendering issue).
• Confirmed that no other letters cause this behavior — only “B”.

Additional Notes:

• The crash is triggered specifically by the autocomplete drop-down when typing “B”.
• No malware or system corruption detected.
• The issue may be related to autocomplete rendering or a corrupted suggestion tied to the letter “B”.
• No relevant files beyond History and Visited Links were found in the profile directory.
• The browser is running on Early Access update stream.
