Hi there! I understand your Swarm II app is not opening after the latest update and it just spins like what Don H reported. Let's work through this together to get it fixed.

First, can you tell me if you see any error messages when you try to open the app, or does it just keep showing the spinning/loading screen indefinitely? Also, have you tried restarting your computer after the update recently?

While waiting for your reply, here are some common initial steps that often help with Swarm II app issues after updates:

1. Restart your PC: Sometimes a fresh start resolves temporary hang-ups.
2. Run the app as Administrator: Right-click the Swarm II app icon and select "Run as administrator" to give it full permissions.
3. Check for pending Windows Updates: Sometimes system components need updating to work smoothly with latest software.
4. Disconnect all Turtle Beach devices temporarily: Unplug your headset or other peripherals, then try launching the app.

If you've already tried those, the next deeper step is to uninstall and reinstall the Swarm II software. This ensures you have a clean and fully updated installation which often helps when the app gets stuck spinning.

To do that:

- Go to Settings > Apps > Apps & Features on your Windows 10 machine.
- Find Swarm II in the list, click it, then choose Uninstall.
- After it's uninstalled, restart your PC.
- Download the latest Swarm II installer directly from the Turtle Beach support site and install it fresh.

This process is recommended to update both drivers and firmware as well, which might fix the issue you’re seeing1 2.

Would you like me to assist you step-by-step with the uninstall and reinstall process, or have you tried that already? Let me know how you’d like to proceed!
