Hi! I see you're having trouble opening the Hello Neighbor app on your Android 13 device. Let's work through this together.

To start, can you tell me what exactly happens when you try to open the app? For example:
- Does the app crash immediately, show a loading screen, or just not respond?
- Do you get any error messages?
- Did the app previously work fine and suddenly stop opening, or is this a fresh install?

Meanwhile, here are a few simple steps you can try right away to resolve app launch issues on Android:

1. Restart your device: Sometimes a quick reboot can clear temporary glitches that stop apps from opening.

2. Clear the app cache and data:
- Go to Settings > Apps > Hello Neighbor
- Tap Storage & Cache
- Tap Clear Cache and then Clear Data
Note: Clearing data may remove game progress if not saved to cloud.

3. Check for app updates:
- Open the Google Play Store
- Search for 'Hello Neighbor'
- If an update is available, install it.

4. Ensure you have a stable internet connection: Sometimes, the game needs online access to start correctly.

5. Check device storage: Make sure you have enough free storage available, as low space can cause app issues.

If you've done these and the problem continues, it could be related to mods interfering or network/firewall settings if you're using some security apps that block internet access. Since you’re on Android, try temporarily disabling any VPN or firewall apps and then open the game.

If you're still facing the issue, feel free to provide the details I asked for, and we'll dig deeper!

Are you able to try these first?
