Fix Warzone 2 Error “Application Unexpectedly Stopped Working” on PC
Source-checked · About 10 minutes
Answer
Record the complete Warzone crash message and when it occurs. Check Activision service status, restart the launcher and Windows, update the game and supported graphics driver, verify or scan the game files in the installed launcher, and test without custom launch options or overlays. Avoid DLL downloads, security disablement, and compatibility tweaks not documented by Activision.
1
Record the crash boundary
Capture the full message, code, launcher, game version, timestamp, and whether Warzone stops before the menu, during shader setup, or in a match. Check Activision service status first.
First, make sure that your game files are complete and not corrupted. Open up your Steam library, right-click Warzone 2, and select Properties.
3
Complete the launcher repair
In Steam use Properties > Installed Files > Verify integrity of game files. In Battle.net use the current Scan and Repair control. Let the selected launcher finish before testing.
4
Remove optional launch changes
Clear custom launch arguments and close overlays, injectors, reshade tools, monitoring hooks, and overclocks. Keep Windows Security and anti-cheat protections enabled.
5
Test the normal executable path
Launch Warzone from Steam or Battle.net rather than changing cod.exe compatibility properties. Confirm whether it reaches the menu with default launch behavior.
6
Update your Windows OS
In case the problem persists, then open up your Windows settings. In the Windows Update section, click on Check for updates and download the latest update before restarting your PC.
7
Verify a representative session
Reach the Warzone menu and complete one training or normal permitted session. Confirm the crash does not return after a fresh launcher start.
8
Escalate with crash evidence
Send Activision Support the complete error, timestamp, launcher, crash stage, Windows and GPU-driver versions, and file-repair result. Do not download replacement DLLs or modify anti-cheat files.

If it does not work
If the expected control is missing, update Call of Duty: Warzone and confirm the account, platform, region, and eligibility before assuming the feature was removed.
If the action changes currency, progress, or account access, stop and use official support instead of guessing from an older label.
