I'm not with Laminar Research, just a fellow simmer in the UK and I have a few questions:-
1. When you state that X-Plane 11 "crashed", did you mean that the X-Plane application shut down back to the desktop, or, did you mean that the entire PC crashed and shut down to re-boot?
2. On face value, your hardware configuration should be OK, but it may be worth carrying out a 'stress test' of your PC to make sure that everything is stable. You can run such a test at the following website:- https://cpu.userbenchmark.com/Software
3. Could you please upload to this post, a copy of your X-Plane 11 Log.txt file which is in the C:\X-Plane 11 folder.
If you're not sure how to upload files to this Q&A post, then please click on the following link to view some instructional PowerPoint slides that I have prepared for this very purpose:- http://questions.x-plane.com/?qa=blob&qa_blobid=14222284191387982694
