I have found using FSLTL, or not using it, does not make a difference; I have found that the sim freezes about 15 or fewer minutes after beginning a flight. I thought initially it was because of a conflict with FSLTL, but alas the freezing occurs whether I use it or not.
NOTE: The sim needs to be shutdown via Task Manager.
I have the same Problem too.
I think MSFS crash if FSLTL inject a new traffic around me..
Without FS Realistic, i have no crash.
