Hi there! I understand you're experiencing a black screen issue specifically when trying to play level 5 in Snail Bob 2, while other levels work fine. Let's get this sorted out together.

First, just to clarify, is this happening when you play the game through a browser on your Windows 10 device, or are you using an app version? Also, have you noticed if the black screen stays completely static, or does anything else appear (like sound or partial loading)?

Assuming you're playing in a browser on Windows 10 with WebKit, here are some steps to try:

1. Refresh the browser and clear cache
Sometimes cached data can cause glitches in specific game levels. Try refreshing the page first (Ctrl + F5 to force refresh). If that doesn't work, clear your browser cache and cookies for the site hosting Snail Bob 2.

2. Check browser compatibility and update WebKit
Ensure your browser and its engine (WebKit) are up to date. Sometimes older versions may struggle with certain graphics in games.

3. Disable browser extensions
Temporarily turn off any ad blockers or privacy extensions as they can interfere with game assets loading properly.

4. Restart your PC
A simple restart can resolve temporary memory or display glitches.

5. Try another browser
If possible, try launching level 5 in another browser like Chrome or Firefox to see if the issue replicates. This helps narrow whether it's browser-related.

6. Check your graphics driver
Make sure your PC’s graphics drivers are updated to the latest version, especially since level 5 might have some specific graphics elements triggering the black screen.

If you have already tried these steps, let me know which ones, and we can go deeper into troubleshooting. If the problem persists after all these, there could be a corrupted game file or server-side issue with level 5, and I can guide you on contacting support or looking for a game update.

Looking forward to hearing back so we can fix this together! Are you satisfied with this troubleshooting plan so far?
