After installing multi-language packages in Laravel, phpstorm still reports an error

Okay, the second execution was successful, but I clearly remember that the first execution was successful. What a shame

Please first go to the directory where this namespace is located to check whether the file of this namespace really exists (make sure your namespace is not written correctly). If it is confirmed that it exists, rebuild the workspace, or delete the project in phpstorm first , re-import and give it a try.
