Troubleshooting Steps

1. Check if the file is present in the correct location. If it's missing, restore it from a backup or reinstall the package that contains it.

2. Verify if the file path is correct and there are no typos in it. Double-check the letter case and directory structure.

3. If you have recently moved the file to a different location or renamed it, update the component or module that depends on it accordingly.

4. Ensure you have sufficient permissions to access the file. If you are working in a shared environment, check with your administrator or IT support team.
