Hey choel,
I have a few questions/suggestions regarding your crash:
- Could you please cause the crash to occur again, and provide the logs from your project’s Saved->Logs folder?
- Try deleting the Saved and Intermediate folders after you grab the logs, then attempt to launch the project again.
- Try opening a copy of the project in the 4.15 preview to see if the crash still occurs there as well.
- If none of these suggestions work, the best course of action here would be for you to migrate each blueprint one-by-one into a clean project, restarting the editor after each migration so you can determine which blueprint is causing the crash. Once you have determined this, you can begin to debug the blueprint and see what could be causing the issue.
