MSFS shuts down on loading flight plan

Hello
All very new to using simbrief and not very technical. I used simbrief on MSFS and it was great and loved it. However since then I have had nothing but trouble. I create a new flight plan, generate it save it however when I go to land it into MSFS all that happens in MSFS shuts down . I tried playing MSFS with out trying to load a simbrief flight plan and it’s fine
I would be greatful for any help as it’s so frustrating

Hi, could you upload the .pln file that is causing the sim to crash? I’ll take a look to see if it also happens on my system.

Cheers,
