Editor crashing when opening an specific level (.umap)

Hi ,

  • Are you able to PIE if you remove the map from the project?
  • What assets do you have in the map?
  • Was this project upgraded from a previous version or was it created in 4.10?
  • Is this project c++ or blueprints?
  • Are you using the source version of the editor or the binary version from the launcher?
