This error message is in Chinese and it roughly translates to: "The requested operation cannot be performed on a file opened in a user-mapped section."

This error occurs when Java is unable to access or open a file located at the specified path. The file may either be missing or the program may not have sufficient permissions to access it.

To resolve this error, you can try the following solutions:

1. Verify that the file exists at the specified path.
2. Check if the file is currently being used by another program or process.
3. Ensure that the program has the necessary permissions to access the file.
4. If the file is being accessed from a network drive, check if the network connection is stable.
5. Try running the program as an administrator
