@WebMaxxximus, Community folder difficulties is only one of many things that potentially cause unexplained CTDs. There was a recent thread here that found that most people, maybe even almost all, have never had a truly “unexplained” CTD. Many of those people found that once they eliminated Community folder causes, all of their CTDs could be explained by older bugs that were found and fixed.
A couple of the most common examples include turning the VRF map on in flight, or pressing the “wrong” button in several Carenado payware aircraft, and both of those issues have long since been resolved.
There’s lots of things that can contribute to CTDs. These include (but are by no means limited to) unstable overclocks, PC parts that work most (but not all) of the time, say a memory module that is 98% reliable, or a PSU that is only 99% reliable. (These are only hypothetical examples, it could be just about anything inside a PC that isn’t in tip-top condition.)
Community issues are, naturally, the top leading cause of CTDs, which naturally can be frustrating because they can be difficult to track down, but the alternative is for you the end-user to never use a 3rd party add-on, or even for Asobo to go so far as to remove the Community folder feature completely.
Anyway, those are the likely reasons that it can appear so random, because it can come from so many different places.
