Hi there! I understand you're having trouble opening Level 650 in Bus Escape when you click to play. Let's see if we can resolve this together.

1. Check for Updates: First, make sure that both your Bus Escape app and your Android system are updated to the latest versions. You can do this by going to the Play Store, searching for Bus Escape, and checking if there's an "Update" button available.

2. Try a Different Access Method: Sometimes, levels may not open directly from the main menu. You can try accessing Level 650 through a different route:
- Go to the Settings menu (the gear icon).
- Look for an option called Level Select.
- Select Level 650 from there to see if you can play the puzzle that way.

3. Restart the Game: Close the game completely and restart it. This can sometimes resolve minor glitches.

4. Clear Cache: If it’s still not working, clearing the cache might help. Here’s how:
- Go to your Settings.
- Tap on Apps or Application Manager.
- Find and select Bus Escape from the list.
- Tap on Storage, and then select Clear Cache.

5. Reinstall the App: As a last resort, if the above steps don't work, consider uninstalling and then reinstalling the app. Just ensure your game progress is saved (check if there's a linked account) before doing this.

If these steps don't resolve the issue, please let me know, and I can look into some higher-level support options for you. Are you satisfied with the solution I provided or do you need further assistance?
