Hey

Does your engine crash every time you open any project, or just this project? Also, have you tried creating a copy of your project and attempting to open it in 4.8 Preview 4? If so, does it work, or does it provide you with the same crash? Would you please be able to go into your project folder > saved > and provide me with the most recent from the crash so that I can further look into the issue you’re experiencing?

Thank you! :slight_smile:
