Sorry to hear that you are having these issues.
I'm going to hesitate to suggest this since as I've said before it's a long, tedious fix, but a total uninstall and reinstall fixed an unplayable (CTD's after about 5 minutes of being in game) game for me.
I'm presuming you are aware of all the standard fixes for CTD's, clearing out your community folder before updates, checking there are no mods that are contributing to CTD's, and while the AI traffic issue is supposedly fixed I'm not sure whether live weather might contribute to some. Apologies if I seem to be trying to teach you to suck eggs...
My issues were none of the above as I ended up running with no mods, no AI traffic and no live weather. I don't know what caused my CTD issue, can only suspect it was a corrupted update. Since I uninstalled and reinstalled, and since since the two subsequent mini patches which happily didn't break anything, I am now running with the mods I use (I only use the Working Title mods, two of which are in my community folder and one of which is installed via the content manager), AI traffic, live weather, and I've flown a bunch of different aircraft in a bunch of different locations. My only issue is that now the game tends to spike my processor temps into the 90's which is a little warmer than before, but average temps are in the 60's and no throttling happening. I start flights in flat screen to program the FMS and then switch to VR to taxi and fly.
So, while I hesitate to recommend you spend 5 or more hours uninstalling and starting over, it did seem to work for me.
Whatever, I hope you get it fixed, because it's actually playing pretty well when it doesn't crash.
