What issue are you seeing?

Environment:

• Windows 11
• Microsoft Store version
• Codex version: 26.707.3748.0

Description:
I accidentally entered the value 1216 in the Codex Settings panel (I don't remember the exact setting name).

After saving the setting:

• The entire UI became massively scaled.
• Huge letters are rendered across the interface.
• The application is almost unusable.

What I tried:

• Uninstalling and reinstalling
• Resetting the Store app
• Deleting LocalCache and Package folders
• Restarting Windows
• Removing local configuration
• Testing both Codex and Codex Beta

Result:
The issue persisted and eventually affected both Codex and Codex Beta.
ChatGPT Classic works normally.

Expected:
The UI should either reject invalid values or provide a safe recovery/reset mechanism.

What steps can reproduce the bug?

I accidentally entered the value 1216 in the Codex Settings panel for font size by mistake.

What is the expected behavior?
