The current meta Minecraft crash questions should be made off-topic: yes/no? seems to agree that Minecraft crash questions should be outlawed with an exception for vanilla crashes.
Now I assume we all agree that even most of our vanilla crash questions are awful and they are typically voted down and closed as unclear.
Now I am not saying that is bad, but as a user of the site, makes me unhappy, since by doing that, I am not actually helping people that came looking for help. Obviously, the people asking all these questions are unhappy as well, seeing that they weren't helped.
IMO, there is typically not that many different things that can cause Vanilla Minecraft to crash, which makes most of these questions duplicates. Now, closing as a duplicate is much more satisfying, since it actually helps people. The problem now is that for many of these questions, finding a sensible, coherent duplicate that actually has an answer is quite difficult.
I am aware that Is there a list of error codes for Minecraft?, actually contains the answer to most of these issues, but this question has one major disadvantage: SEO. As in quite often, it is low in the search results even when searching for a header of that particular answer. For search terms such as
ig4dev64.dll, it does not show up at all, and we had two questions about this issue within the last 24 hours (both of which are now on hold).
Now, instead of trying to curate and using a single all-encompassing answer to all Minecraft errors, I suggest creating questions containing minimal (non-)working examples of the crashes, including a clear question title. These should be easily findable with the correct keywords, and serve as clear duplicates. Note that question age should play no part in closing as duplicate, only quality.
As an example (this meta is really more of an afterthought of that), I have created and CW-answered the following, seeing that the duplicate I found was far from a MWE.
