I've met same situation when I take off from RJBB, also CTD at same point shortly after take off.
And finally I found that NONE of the RJBB scenery on sale now is compatible with MSFS2024.
So, some of CTDs also may caused by incompatible scenery s.
My situation almost like yours, but I met crashed once in approach, twice in climbing
The biggest problem now is I can't figure it out if inibuilds a350 caused the CTDs
I brought A350 last week, and till now I've only finished ONE flight
btw, msfs2024 UPDATED SU2 BETA today
Do you use FSLTL with VATSIM or something else?
I met with CTDs these days with FSLTL, and the game just crashed randomly
FSLTL sounds maybe the reason
