Why does my blender file close a few seconds after opening it and how do I fix this? When I open a blender file, my project is visible for a few seconds while I can't make any changes to it, and then it closes. Does anyone know how to fix this? This doesn't happen to all of my blender files by the way. I can also start a new project.
This may be caused by any single object in your file. Try opening a new project, click File -> Append, and add the objects from your corrupt file chunk by chunk or piece by piece. This way you can narrow down, if or which single object causes Blender to crash.
