Hi! I see that your Hill Climb Racing 2 app on your Windows device stopped launching after an update. Let's get to the bottom of this together.

First, could you please tell me:
- Are there any error messages or does the app just fail to open?
- Did it stop working right after a specific update?
- Have you already tried restarting your computer or reinstalling the game?

In the meantime, here are some initial steps to try:

1. Restart your computer: This can clear any temporary glitches.
2. Check for Windows Updates: Sometimes, game updates require your system to be up to date.
3. Update the Microsoft Store app: Go to Microsoft Store > Downloads and updates > Get updates, to make sure the game and Store app are current.
4. Run the Windows Store Apps troubleshooter:
- Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters.
- Select "Windows Store Apps" and click "Run the troubleshooter."
5. Clear the Microsoft Store cache:
- Press Windows key + R, type wsreset.exe, and press Enter.
- This will clear your Store cache which might fix launch issues.
6. Check your internet connection: A stable connection is needed to authenticate the game after an update.

If none of these work, you might need to try reinstalling the game. If you do this, please ensure your progress is saved through a connected account (like Facebook or Google) before uninstalling.

If you have already tried some of these, please let me know which ones, so I can suggest the next steps.

Are you satisfied with this troubleshooting plan so far?
