I’ve been using UE for the same project for several years with only occasional crashes. However, recently I’ve started suffering from much more regular crashes, generally between 1 - 3 times a day, but rarely while editing the same thing… Sometimes I’m editing random blueprints, sometimes I’m messing around with UI stuff, sometimes I’m tweaking a material or texture. It’s very odd, rather frustrating, and I don’t have a clue how to diagnose what’s going on! 
I’m guessing it’s some change I made to the project in the last couple of months, but I’m a bit in the dark to be honest. Fingers crossed you’ll be able to help me understand and fix whatever’s causing it.
What info do you need from me? Do I need to upload logs and stuff somewhere? Or should I just copy/paste the relevant logs here?
