he directory '/Users/harsheetgundecha2007/Documents' could not be created. Please check the validity of the directory path or parent directory protection or permission rights.
If this is happening on launch, it sounds like your system is configured for that to be the default folder for Documents but it doesn't exist yet and the user that the process was launched under doesn't have permission to create it. Character Animator will need permissions to create and open a default project in the created directory to avoid this error.
