Hi there! I’m sorry to hear June’s Journey isn’t opening on your Chromebook. Let’s figure this out together. Just so I understand better, when you say the app won’t open, do you mean it doesn't launch at all, or does it get stuck on a loading screen? Also, are you using the June’s Journey app from the Google Play Store on your ChromeOS, or are you playing via a browser?

Meanwhile, here are some quick steps you can try:

1. Restart your Chromebook: Hold down the power button for about 10 seconds to fully shut down, then turn it back on. This can clear temporary glitches.

2. Clear Cache and Cookies: Since June’s Journey often runs through a browser on Chromebooks, clearing your browser's cache and cookies can help. Go to Chrome settings > Privacy and Security > Clear browsing data > select "Cached images and files" and "Cookies and other site data," then clear them.

3. Check for Updates: Make sure your ChromeOS and Google Play Store apps are up to date. Sometimes updates fix compatibility issues.

4. Disable Extensions or Ad-blockers: If you have any browser extensions or ad-blockers, try disabling them temporarily, as they can interfere with the app loading properly.

5. Reinstall the App: If you are using the Google Play Store app version, try uninstalling and reinstalling June’s Journey.

If these initial steps don’t work, I can guide you through some other checks related to app permissions or account logins.

Could you let me know which of these steps you've tried or if the problem behaves differently? That way, I can help more precisely!
