Plagued with CTDs. How can I find root cause

Great suggestions, and I really appreciate it. One of the things that have kept me positive is the awesome community helping each other through the rough patches (and there have been a lot of them).
I will remove everything from Community, but thought I would start in the reverse order, so I blew out all the liveries for starters. I was ready for the sim to crash on my next landing approach, but alas, I was actually able to land and park. I know one flight doesn’t mean it’s solved, but hoping it was that simple. If I get another CTD, then everything will go and I’ll add stuff back in one at a time.

Also, I’m not thinking it’s a location bug because it was doing it in random locations, but something to watch for. In any rate, I’ll give it the time and patience needed to solve it.
