Hi there! Thanks for reaching out. To get us started, could you tell me if you're experiencing this issue in a web browser on your Windows device, or are you using a PBS KIDS app? Also, is this happening with all videos and games or just specific ones?

While you answer, I can walk you through some quick checks that usually help in situations like this.

1. First, try refreshing the webpage or restarting the app you’re using. Sometimes this clears small hiccups.

2. Make sure your Windows 10 is up to date by checking for system updates. Also, updating your web browser (since you’re using WebKit-based browser) helps ensure compatibility.

3. Clear your browser's cache and cookies, which can sometimes cause loading problems.

4. Check your internet connection to verify it's stable and fast enough to stream videos or load games.

If those don't resolve it, a more targeted step would be to disable any browser extensions or security settings that might block content (like ad blockers or privacy blockers) temporarily to see if that helps.

Let me know what you've tried so far or if you want, I can guide you through these steps one by one!
