Hi there! I’m Pierre, happy to help with your issue in the Isekai app's "Monster Holiday" event. To get a better picture, could you tell me if this problem happens just in this event or also in other parts of the app? Are you receiving any error messages or does the game simply not respond when you try to attack or interact?

Meanwhile, here are a few initial steps that often resolve such interaction issues:

1. Restart the App: Close the Isekai app completely and reopen it. This can clear temporary glitches.
2. Check for Updates: Make sure your Isekai app and your Windows system are fully updated.
3. Clear Cache (if applicable): Sometimes cached data conflicts cause interaction bugs.
4. Verify Network Connection: A stable internet connection is essential for events to work properly.
5. Re-login to Your Account: Logging out then back in might reset session issues.
6. Disable any overlays or third-party software that may interfere with input.

Could you please try these and let me know if any progress happens? If not, we can explore deeper settings or account issues.
