I’m looking into this issue now. It looks like this crash is happening in 4.6.1. If you were able to open the project previously in 4.6.1, but you can’t open it now, it’s probably due to a corrupt asset. Samaed’s crash report makes it seem like a skeletal mesh component causing the crash; if you try removing any blueprints that have skeletal meshes attached from your project (store them somewhere else on the computer for the time being), are you able to open the project?
EoinOBroin, if you’re seeing the exact same crash report, I’d recommend the same measures. If your crash report is different, then the cause of your crash probably is too.
I actually got a different crash report (it was the same up until the “Assertion failed:” part), I reported it when it occurred twice. I remember that I was using my xbox controller in the editor play mode to playtest, and I disconnected it a few seconds after ending play, however I think one of the analog sticks was slightly moving as when the controller got disconnected, it was almost like the fov in editor view went to maximum (or minimum). I couldn’t get rid of this after multiple attempts of turning on and off the controller, attempting to reset the view. I eventually quit the project, and it loaded back up just fine, but as soon as I played or simulated, the crash occured. (Also using 4.6.1). Luckily I had a backup from a few hours before, so I replaced the project and all is well now!
