Hi there! I understand you're having trouble with the Word Collect app where the letters inside the circle aren't loading. To get a clearer picture, could you tell me a bit more? For example:

- Does the app open normally, but just the letters don't show up in the puzzle circle?
- Have you noticed if this happens on specific levels or all the time?
- Are you connected to the internet when this happens?
- Have you tried restarting the app or your Mac already?

Meanwhile, here’s a straightforward set of steps commonly helpful for this kind of situation on your Mac running OS X 10.15.7:

1. Restart Your Mac: Sometimes, a quick reboot can clear temporary glitches that affect app performance. Click the Apple menu and choose Restart, then open Word Collect again.

2. Ensure Network Stability: Word Collect may require an active internet connection to load game data. Confirm your Wi-Fi is stable by opening a webpage or trying another online app.

3. Quit Background Applications: Close other apps that might be consuming resources to ensure Word Collect has enough memory to load properly.

4. Check for App Updates: Open the Mac App Store, go to the Updates tab, and see if there’s a newer version of Word Collect available. Installing updates often fixes bugs like missing letters.

5. Reinstall the App: If none of the above works, try deleting Word Collect from your Applications folder and reinstalling it fresh from the Mac App Store.

If you’ve already tried any of these, please let me know so I can suggest more advanced steps. Also, if there’s any error message or unusual behavior you see, sharing that would help pinpoint the issue.

Are you satisfied with these steps so far, or shall we dig deeper?
