how to fix msedgewebview2.exe application error ?

Identify the application launching WebView2, then repair or disable that application; msedgewebview2.exe is a shared Windows runtime used by apps such as Widgets, Teams, Office, Outlook, and many others, so removing the executable itself is not the correct fix.^1^

1. Identify the application causing the three errors

1. Press Ctrl+Shift+Esc to open Task Manager.
2. Select Processes, then reproduce the problem by opening a game.
3. Look for WebView2 processes grouped beneath an application. On current Windows 11 versions, Task Manager normally groups WebView2 processes by their parent application.^1^
4. Also check Startup apps for software that starts with Windows—particularly game launchers, overlays, hardware utilities, chat applications, or widgets.
5. If one application consistently appears immediately before all three dialogs:
   • Open Settings → Apps → Installed apps.
   • Select … beside that application.
   • Choose Advanced options → Repair, if available.
   • If Repair is unavailable, update or reinstall that application from its publisher.

Do not manually delete msedgewebview2.exe. WebView2 is preinstalled on Windows 11, and applications that depend on it may reinstall it automatically.^1^

2. Test for a startup-service conflict

Because the error occurs at sign-in and when games start, perform a clean boot:

1. Press Win+R, enter msconfig, and press Enter.
2. Open Services.
3. Select Hide all Microsoft services—this is important to avoid disabling Windows services.
4. Select Disable all, then Apply.
5. Open Startup → Open Task Manager.
6. Disable every enabled startup item, noting which ones were enabled.
7. Restart Windows and test the same game.

A clean boot starts Windows with essential drivers and startup programs only. If the error disappears, a disabled third-party service or startup application is responsible.^2^

Re-enable half the disabled items, restart, and test again. Continue by halves until the responsible item is isolated. Leave that item disabled and update, repair, or uninstall it. After testing, return to System Configuration → General → Normal startup and re-enable the unaffected startup items.

3. Repair the shared components

If the error still occurs in a clean boot:

1. Close Microsoft Edge and other WebView2 applications.
2. Go to Settings → Apps → Installed apps → Microsoft Edge → … → Modify.
3. Approve the administrator prompt and select Repair while connected to the internet. Microsoft states that Edge browser data and settings should not be affected.^3^
4. Restart Windows and test again.
5. If WebView2 is reported as missing or damaged, download and install Microsoft Edge WebView2 Runtime from Microsoft’s WebView2 consumer download page. Windows 11 normally already includes this runtime.^4^

4. Repair Windows components if the crash remains

Open Terminal (Admin) and run these commands in order:

DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow

Wait for each command to finish completely, then restart. DISM repairs the Windows component source used by SFC, and SFC checks protected system files.^5^

5. Collect the decisive crash details

If none of the above resolves it:

1. Press Win+R, enter eventvwr, and press Enter.
2. Open Windows Logs → Application.
3. Find an Error at the exact crash time, usually with source Application Error.
4. Record:
   • Faulting application
   • Faulting module
   • Exception code
   • Application and module versions
5. Also check whether a third-party antivirus or endpoint-security product logged a WebView2 block. Security tools can terminate WebView2 renderer or GPU processes, and Microsoft recommends checking Application/System logs for initialization failures and blocked-execution events.^6^

The exact late-October 2026 0x80000003 breakpoint is not currently identified in Microsoft’s Windows 11 release-health information as a documented OS-wide known issue, so the parent application and faulting module are needed to distinguish an app-specific crash from a runtime or security-software conflict.^7^
