JavaScript Error: 'SyntaxError: Identifier 'CryptoJS' has already been declared'

This error occurs when you are trying to declare a variable or import a module named 'CryptoJS' multiple times in your code. In JavaScript, you can only declare a variable once within the same scope.

To fix this error, you need to ensure that you are only declaring the 'CryptoJS' identifier once in your code. Here are a few possible solutions:

1. Remove duplicate declarations: Check your code for any duplicate declarations of the 'CryptoJS' variable and remove the redundant ones.

2. Use a different variable name: If you need to use 'CryptoJS' multiple times in your code, consider using a different variable name for subsequent declarations.

3. Check for conflicting imports: If you are importing a module named 'CryptoJS' from different files, make sure to import it only once and remove any duplicate import statements.

By resolving the duplicated declarations, you should be able to fix the SyntaxError.
