Still an issue in 2025. Missed an approach, went to pick a new one, hit the load button on FMC and it CTD.

Exactly the same still happening in 2025 if you change SPD/TRANS or SPD/RESTRICTION in the VNAV DESCENT page while descending. You need to do it before descending, otherwise the sim freezes.

This just happened to me yesterday in SU5, still not fixed.
