If there are issues with Steinberg and V-control connecting/crashing, it may help to reset the V-control Controller in Device Setups.
1. Go to "Devices" and open the "Device Setup" window.
2. Select V-Control Pro from the list and click the "Minus" sign to remove the device.
3. Restart Cubase.
4. Click the "Plus" sign and select V-Control Pro from the list then open the Raven app.
This will reset the controller setups in V-Control Pro and Raven and the Device Setups in Cubase.
