Hi there! I’m sorry to hear about the issues you're having with the Hidden City game. It sounds really frustrating, especially after hitting that anniversary button and losing your gifts and energy. Let's see if we can get this sorted out for you.

Could you tell me more about the situation? For instance, did this start happening after a recent update? Also, have you tried any troubleshooting steps like restarting your device or reinstalling the game?

In the meantime, here are some steps you can try to address the crashing issue:

1. Restart Your Device: Sometimes, a simple restart can refresh system resources and help with performance issues.

2. Check for Updates: Make sure both your game and your Windows operating system are up to date. Outdated software can often lead to crashes.

3. Clear the Game Cache: If your game has a cache or storage option, try clearing it. This can help in case there are corrupted files.

4. Reinstall the Game: If the problem persists, uninstalling and then reinstalling the game might help. Just ensure to log into your account to recover your progress.

5. Check Known Issues: You can also visit the G5 Games support page to see if this is a known issue with a suggested workaround.

Please give these steps a try, and let me know how it goes! If you're still having trouble, we can dig deeper into the issue together. Are you satisfied with this plan, or is there something else you’d like to discuss?
