Crash when open a 4.8 project

Confirmed to be the issue:
A Hit Result (or any other struct) split in a Blueprint Function Library, during the conversion from 4.7 to 4.8.

struct splits in other blueprints cause no issue.
re-creating the split structs in the 4.8 project causes no issue.

Ok, nice to see you found the problem.
@: maybe you can combine the bug report “UE-17326” with the Davero ones.
