Hi! I understand that the Subaru ad keeps popping up and then locks your screen while using the Traffic Escape app on your Windows 10 device with WebKit. Let’s try to get this sorted out for you.

To start, could you clarify a bit for me?
- Is this Subaru ad appearing as a popup inside the Traffic Escape app, or does it appear as part of your browser or system notifications?
- When the screen locks, do you mean the entire computer locks (requiring a password or something to resume) or just the app freezes and becomes unresponsive?

Meanwhile, here are some initial steps we can try to troubleshoot this issue:

1. Clear Cache and Cookies for the App or Browser: Sometimes ads cause glitches if cache data gets corrupted. Since you are on WebKit, clearing your browser cache might help if Traffic Escape runs through a browser. You can do this by:
- Opening browser settings
- Finding Privacy or History settings
- Selecting "Clear browsing data" including cache and cookies

2. Check for Software Updates: Are both the Traffic Escape app and your operating system fully updated? Sometimes bugs like this get fixed through updates. Go to your app’s settings or Microsoft Store (if app installed from there) to check for updates.

3. Temporarily Disable Ads or Popups: If Traffic Escape has an ad removal option or a premium version, trying that could remove these interruptions. Also, check your Windows notifications settings to see if popups can be limited.

4. Scan for Malware: Though unusual for a trusted app, if unexpected ads pop up persistently and lock your screen, performing a malware scan with Windows Defender or another trusted antivirus can rule out any malicious cause.

5. Restart your Device: A fresh restart can clear temporary glitches causing screen lock or app freezing.

If these don’t resolve the issue, I can guide you through deeper troubleshooting such as checking app permissions or possible conflicts with other software.

Let me know how the screen locking behaves more specifically, and what you’ve tried so far!
