I have made several flights and have been able to repeat the problem mentioned.
After a flight, I turn off the engines, connect the GPU, etc. and prepare for the next flight.
So I plan with Simbrief and then load the flight plan into the 350. Then I go to the INI page and want to download the data from there. When I want to transfer the data to the FMS and click the button, everything stops and no more input is possible.
I can switch between the different views, but nothing else happens, not even after 30 minutes.
Solution: I go to the main menu and restart, then everything works fine until the next landing.
Good evening
