Thank you all for trying this out.
Does anyone use the G1000 Mod by Workingtitle? Because I narrowed my CTD down to aircraft that use it.
Aircraft equipped with the G3X or G3000 are not affected.
better switch it back to OFF… it cause random issues…
In theory it bring better performance, in praxis it bring trouble into the world 
Latest example are the reports where users run with this into crash in Free View.
Because the Glasscockpits…
- the G1000 would explain that. Garmin replacement , or simple sayd a mod, was one of the cause in the mentioned old topic.
@CasualClick you did same as me… and I found no issues too.
I have used it since it came out never had a problem with it.
there is a thread about it, yes, more people have problemes with it, and it counts as an
addon too.
again with any ctd’s or other problems, fly on pure default, to see if it is maybe an addon.
That did it. After uninstalling the G1000 NXI mod it worked.
Then I reinstalled it, tested again and it still worked.
So I assume it got corrupted somehow.
Problem solved
