Specifically, CTD a few seconds after clicking [FLY] v 1.18.14.0

There are too many threads about CTDs, so I find it hard to find solutions.
My communty folder is empty. I am not selecting previously saved flight, but start new ones - - - World Map >> set up flight >> [FLY]
or one of the training flights >> [FLY]
and every time I get a CTD a few seconds later.
Thanks to any who shares this experience and has any ideas to share.

I sympathise with the issue you describe.
The forum is not best served by a new thread for every individual CTD.
The main thread to post in is, perhaps, Repeated CTD's 1.18.14.0
