tds gtn750xi app not opening

[Ryan]

Hi with MSFS off double clicking destop TDS GTNXi shortcut results in the app opening for approximately 2 seconds then closing. Just using standard Microsoft Windows 11 antivirus. Ive tried opening with antivirus on and off. With MSFS running the Garmin 750 is there but the screen is blank. At one point it was flickering with my name and 'continue' visible.
