I'm on N12 And the game is crashing out of the blue at this point in the save file uploaded . I've tried turning off all research as I thought something was causing it there, but it's not working. The only thing is that this specific save started on N11, and I transferred it over, which I don't know if that is doing something or not.
In your save file, find this:
- type: STR_DISTRESS_CALL
region: REGION_DISTRESS_CALL_DESERT
race: STR_SECTOID_INDUSTRIAL
nextWave: 0
nextUfoCounter: 0
spawnCountdown: 105
liveUfos: 0
uniqueID: 218
missionSiteZone: 18
and change `missionSiteZone: 18` to any lower number, e.g. `missionSiteZone: 17`
