Describe the bug

For the last ~2 weeks I have been unable to load my simbrief plan into the FMGC.
When selecting INIT REQUEST I am receiving an INTERNAL ERROR.

Loading simbrief into the Flypad works fine.

Expected behavior

Select Init request from FMGC INIT page
Latest simbrief plan is loaded into the FMGC

Steps to reproduce

1. create a flight plan in simbrief
2. launch simulator and start a new flight
3. connect batteries and external power
4. request simbrief in Flypad (succeeds)
5. go to AOC and load simbrief (succeeds)
6. return to FMGC INIT and select INIT REQUEST
7. Error received

Additional info (optional)

Entering all flight plan data manually works without problem.
When filling data, noticed that in the PERF APPROACH page, the transition altitude is shown as NaN. Might be unrelated

Closing as after a clean install of A32NX the issue seems to be corrected for now.
