UE4.19.2 crashes on when trying to open level

I have been trying to create a VR walkthrough of a house using the standard FirstPerson template using UE4 4.19.2 on a Mac. I have part built the models and then created a new level from it.

Having worked on the new level models all day, saving as I go, UE4 decided to crash and now the whole level won’t open and crashes UE4 every time! I can open the original level.

Does anyone know if its possible to get the new one to open again or have I lost the lot?

check the saved folder under the project folder. Look for the map file with the date. Rename it and save over the corrupted file.
