After update 6 I had 4 flights. 3 of them ended with a crash (of the PC). One to the desktop and 2 to Nirvana.
I always fly the latest experimental version.
One crash after switching on the APU after landing and two just like that.
You may need to be more specific in your title or post about what aircraft you are experiencing the crashes with.
It sounds like you are talking about the Fly By Wire A320? My first guess would be to clear out your Community folder apart from the FBWA320 and see if it changes anything (possible mod conflict). Then maybe swap to the stable version of the mod and see if anything improves?
Experimental is prone to bugs and I don’t believe they offer support for it, as it is for testing purposes. They welcome feedback and bug reports though, probably via their Discord.
I am also experiencing many many CTDs…never had this issue before. Every second flight now. 
So to the best of my knowledge, FBW only makes the A320 so far. I deleted the community folder before the update and then reinstalled the FBW.
Again after the crash.
I also flew crash-free with this version. The crashes always came in different places, not reproducible so I don’t see any point in switching to another.
After update 6 I had a crash with a c172 classic. I think on my case the ctd comes from live traffic and memory cash. But I am not sure.
So perhaps on your side the fbw a320 is not the cause of your ctd. Perhaps…
If you don’t see a point in swapping from the unstable experimental branch to the stable branch then there’s nothing else I can suggest to help.
Im getting CTD based in location. Flying around DC will knock me out. Spawning at KADW is and instant CTD. No addons flying any stock aircraft.

… and it goes on and on and on - slowly it’s no longer fun. The only thing is: the crashes cannot be provoked or herfeitable
