I just entered that flight into a SimBrief flight plan using MSFS 2024 EFB Simbrief Dispatch.
After checking I had my SimBrief Pilot ID correctly set in the Inibuilds EFB Options, I was able to load the flight plan.
In the MCDU, I used Init request to again enter the flight plan into the MCDU. No problems. However when I exited MSFS 2024, the system crashed, requiring a CTRL ALT DEL close
I have read on the internet there may be problems in the A320 Inibuilds when flight plan loaded by Init Request in the MCDU, causing the crash on exit.
We dont believe this is a SimBrief flight plan issue.
Best to pursue this in the MS/ASOBO forums.
Cheers
Ian
