CrashReporter User Descriptions:

  • Launching the Editor
  • Booting up the engine. Unable to get passed this error.
  • maybe at some point c drive was full. I just verified installation with launcher.
  • updated graphics drivers, tried to sync and launch the game, crash
Steps to Reproduce

1. Create a test project based on one of the templates
2. Open the project in the editor
3. Close the editor
4. Replace the CachedAssetRegistry.bin file in your project's Intermediate folder with an empty (0 byte) file of the same name. (in the binary distribution of the engine, this file is under C:\Users\<USERNAME>\AppData\Local\UnrealEngine\<VERSION>\Intermediate)
5. Launch the project's editor again. It should display an error message when it tries to load the empty cached asset registry, and crash when you close the message.
