Without detailed information on how this is setup or details to reproduce the crash this may be pretty hard to diagnose. Looking at the logs I can tell you the troublesome assets, but that doesn’t tell me much more than that.
Doing a search in our system I found a call stack that was very similar, aside from the asset name causing the issue. This was reported with UE-22245. This appears to not be reproducible any longer in 4.11. Can you try making a copy of your project and opening it with 4.11 P4 that is available via the launcher and see if the issue is still showing. If so, this will be fixed with that version and if anything can rule out if this is the same issue as the one that has already been reported.
Let me know.
