Hey -
Can you provide the callstack and log files from your crash? Additionally, where are you making the call to this function? Are you able to reproduce this issue in a new, clean project with no additional content? If so, please include the setup steps to help me investigate and reproduce the issue on my end.
Without the callstack or a way to reliably reproduce the issue, we are unable to take further action with this issue. If you are able to provide this information, please feel free to leave a comment to reopen the thread.
Cheers
