Hi there! I understand you're facing an error code 500 on the RoadReady app, and it's stuck on saving your last drive, not allowing you to save or exit the screen. Let’s work through this together.

First, just to clarify:
- Are you connected to a stable internet connection when this happens?
- Have you tried exiting the app forcefully or restarting your device?

Meanwhile, here’s a step-by-step approach that usually helps with this kind of problem on Android 10 with WebKit:

1. Clear App Cache and Data
- Go to your device’s Settings > Apps > find RoadReady.
- Tap on Storage > then choose Clear Cache and, if needed, Clear Data (this may log you out, so have your login info handy).
This can resolve corrupted cache or incomplete data issues causing error 500.

2. Force Close and Restart the App
- After clearing cache, go back to Settings > Apps > RoadReady and tap Force Stop.
- Then re-open the app and try saving the drive again.

3. Update the RoadReady App
- Ensure your RoadReady app is the latest version; outdated versions can cause server errors.

4. Reinstall the App
- If all else fails, uninstall the RoadReady app completely and then reinstall it from the Google Play Store. This often resolves most issues by refreshing the app environment1 2.

Also, sometimes this error can result from server-side issues with RoadReady; if after trying the above steps it still doesn't work, it might be worth reaching out to their support at [email protected] for confirmation if there's a temporary outage or known issue.

Try these and let me know how it goes. If it’s still stuck, I can guide you through some more advanced options! Are you satisfied with the solution I provided?
