This error occurs when Corona fails to correctly save final autosave EXR file.
Possible causes:
- You’ve ran out of free hard drive space
- The autosave file path is pointing to a non-existent location
- The autosave file path is pointing to a network location/removable device which is unavailable now
- The autosave file path is pointing to a location to which the user does not have appropriate write/modify permissions
Solutions:
- Make sure the path destination still exists
- Make sure you have enough free space on your hard drive
- Make sure the entered file path is reachable and can be written in/modified
