Hi there! I understand that when you open the Purp app, it starts to load but then suddenly says "Purp keeps stopping." Let's work through this together and get it running smoothly on your Android 10 device.

First, I have a couple of quick questions:
- Did this issue start recently after an update or installation?
- Have you tried restarting your device already?

Meanwhile, here are some simple steps we can try:

1. Clear Cache and Data of the Purp App
- Go to your device's Settings > Apps or Apps & notifications > find Purp.
- Tap on Storage.
- First, tap "Clear Cache" and then "Clear Data" (note: clearing data may log you out, so keep your login info handy).
- Try opening the app again.

2. Restart Your Device
- Sometimes a quick reboot can resolve temporary glitches.

3. Update the App
- Check the Google Play Store for any available updates for Purp. An outdated version may cause crashes.

4. Reinstall the App
- Uninstall Purp completely.
- Restart the phone.
- Reinstall Purp from the Play Store.

If you've already done any of these, please let me know which steps, and we can try some further troubleshooting like checking for OS updates, conflicting apps, or permissions issues.

Are you comfortable trying these first?
