This could be the simconnect issue.
You may want to do a search for “simconnect CTD” if you want some more information.
It should be corrected by ASOBO soon.
I had this issue when I first bought LEIB from sim wings
I raised a ticket due to CTD at this airport, they advised to delete my rolling cache, after I did that it fixed it and never had problems with this airport after that
Just something you can try, sorted it for me
