Hello,
- Try upgrading to 4.10, and then 4.11 to see if this fixes your crash. There are various bug fixes between 4.9 and 4.11, so it is possible that your crash could be resolved.
- Could you provide the logs from your project’s Saved->Logs folder?
- Try deleting the Saved and Intermediate folders from your project and then opening it.
Let me know if any of these solutions help.
