Quick answer: Windows app crashing on Chrome after update is usually caused by a broken app-to-browser handoff, stale site data, or an extension conflict introduced by the update. Clear the app’s Chrome site data, test the app in Incognito, and re-enable the app’s browser permissions if the crash started right after the update.

Quick Fix Checklist
- Close Chrome completely and reopen the app from a fresh browser session.
- Clear the app’s site data and cookies in Chrome for that specific app domain.
- Test the app in Incognito to rule out extension conflicts.
- Disable recently added or updated Chrome extensions.
- Check the app’s permissions for pop-ups, redirects, and third-party cookies.
- Sign out of the app, then sign back in after the update.
Causes
When a Windows app starts crashing on Chrome after an update, the issue is usually tied to the browser profile or the app’s stored web data rather than Windows itself. The update can change how the app loads, which exposes a conflict in saved session data, permissions, or an extension.
| Cause | What it means | Fix |
|---|---|---|
| Stale app site data | Old cookies, local storage, or cached app data no longer match the updated app | Clear the app’s site data in Chrome |
| Extension conflict | An extension blocks scripts, logins, or embedded app components after the update | Test in Incognito or disable extensions |
| Browser profile corruption | Your Chrome profile keeps loading broken app settings or saved state | Create a new Chrome profile and retest |
| Permission change after update | The app now needs pop-ups, redirects, or third-party cookies that are blocked | Adjust site permissions for the app |
| App-side update mismatch | The app updated, but Chrome is still using an older embedded session or login state | Sign out, clear data, and sign in again |
Step-by-Step Fix
- Reload the app in a fresh Chrome tab. Close every tab that has the app open, then open Chrome again and launch the app from its normal sign-in page.
- Clear the app’s site data. In Chrome, open the site settings for the app domain and remove cookies, local storage, and cached data for that site only.
- Test the app in Incognito mode. If the app works there, the crash is likely caused by an extension or saved browser profile setting.
- Disable extensions one by one. Start with ad blockers, script blockers, password managers, and privacy tools, then retest the app after each change.
- Check site permissions. Make sure the app is allowed to open pop-ups, use redirects, and store site data if it depends on those features.
- Sign out and sign back in. A fresh login can replace a broken session created before or during the update.
- Create a new Chrome profile. If the app still crashes, open it from a clean Chrome profile to bypass corrupted browser-specific settings.
Still Not Working
- Reset only the app’s Chrome data. Remove the site’s stored data again and confirm the app is not being restored from a saved session.
- Try the app in a different Chrome profile. This helps confirm whether the crash is tied to your current browser profile.
- Check whether the app has its own update. Some Windows apps that run through Chrome need a matching app-side update before they stop crashing.
- Review the app’s admin or security settings. If this is a managed app, a policy change may be blocking the browser handoff after the update.
- Reinstall or repair the app from its own updater. Use the app’s built-in repair or reinstall option if it has one, then test again in Chrome.
Frequently Asked Questions
Why does my Windows app crash in Chrome only after an update? The update often changes the app’s web session or loading behavior, which can expose stale site data, blocked permissions, or an extension conflict.
Will clearing Chrome cache fix a Windows app crashing on Chrome after update? It can help, but clearing the app’s site data is usually more effective than clearing all browser cache.
Why does the app work in Incognito but crash in normal Chrome? That usually means an extension or saved Chrome profile setting is interfering with the app.
Should I remove all Chrome extensions? Not always. Start with the ones most likely to affect app scripts, logins, or page loading, then narrow it down.
Do I need to reinstall Chrome? Usually no. A new Chrome profile or clearing the app’s site data is the better first step for this issue.
