I was asking about the tablet/touchscreen not to give you an alternative way to play but to see if you had any such devices plugged into your PC as a possible cause of the problem rather than your Xbox controller and flight controllers themselves.
I couldn’t tell you why it’s working after you went to bed even though nothing was changed, we didn’t change anything on our side.
If it starts happening again, I would go right back to basics, unplug all controllers, check for the issue - if there’s no issue - plug one thing back in - test again. Plug the Xbox controller in last. See what happens if you have just the xbox controller plugged in but not your flight controllers as well.
If we can identify what combination of things plugged in is causing the problem it will help us pinpoint the exact problem.
