Hi there! Thanks for reaching out about the PhiGolf app crashing when it gets to device selection. That definitely shouldn't happen. To help you better, could I ask a couple of quick questions?

1. Are you using the latest version of the PhiGolf app on your Windows 10 device?
2. Have you tried restarting your PC or reinstalling the app yet?
3. Is your Bluetooth turned on and ready since device selection often involves connecting via Bluetooth?

In the meantime, here are some step-by-step things we can try to fix the app crash issue:

1. Update the app: Make sure you have the latest version installed. You can uninstall and then reinstall to get the newest release.
2. Restart your computer: Sometimes a quick reboot refreshes Bluetooth and system resources.
3. Check Bluetooth: Ensure your Bluetooth is enabled and the PhiGolf device is turned on and in pairing mode.
4. Run app as administrator: Right-click the PhiGolf app shortcut and choose "Run as administrator" to avoid permission issues.
5. Check firewall and antivirus settings: Sometimes these can block app connections; try temporarily disabling or setting exceptions for PhiGolf.
6. Update Bluetooth drivers: Go to Device Manager > Bluetooth and update your drivers to the latest version.

If the app still closes abruptly during device selection after trying these, please let me know. We can then explore advanced troubleshooting or look for any known compatibility issues specific to your Windows build.

Looking forward to your reply and getting this sorted out!

Are you able to try these steps and let me know how it goes?
