Hi there,
The purpose of this step is to let others (especially the development team) know exactly what you did to experience the issue you had.
Are you starting your flight on the ground at an airport cold and dark, or on a runway, or airborne?
I noticed that you have not disabled your mods and add-ons. Could you try this again in safe mode? Try opening MSFS, pressing Alt+F4 on your keyboard while MSFS is loading, and then restarting MSFS. You should be promoted to start MSFS in safe mode. When you do that, all of your add-ons will be temporarily disabled for that flight. Could you try that and report if your avionics screens are still turning black?
