SHORT ANSWER

Use a rename-and-test reset for Counter-Strike: Condition Zero: preserve the original files, allow the game to generate defaults, and restore settings selectively. Never delete the whole game directory or synchronize a broken config back before the clean test.

Before you change anything

A legitimate Steam installation or dedicated-server installation for Counter-Strike: Condition Zero.
A backup of every file that will be changed.
Access to the local client console or the dedicated-server console, as appropriate.

Version-specific procedure

Exit Counter-Strike: Condition Zero and pause Steam Cloud synchronization only if it is actively restoring the suspect file.
Make a dated copy of user configuration outside the Steam library.
Rename only the suspect config or autoexec file; do not remove maps, assets, or unrelated save data.
Launch the game and test the smallest reproducible case with generated defaults.
Reintroduce groups of settings, restarting between groups, until the conflicting line is isolated.

Verify the result

The game generates or uses defaults without parsing errors.
The issue is tested before any old line is restored.

Rollback

Exit the game, remove the generated test file, and restore the original filename from the dated backup.

Common pitfalls

Cloud sync can reintroduce the old file; inspect sync prompts instead of accepting them automatically.
