everything is smooth, entering facilities and then leaving to the menu but when I try to enter flight mode it all crashes. I haven't been able to root out the cause at all and it keeps happening every time I try to enter flight mode.
using windows and non-steam version of KSP 1.12.3

any help to find & fix the cause would be greatly appreciated!
