Error: EPERM: operation not permitted, unlink '/path/to/fil…

The operation attempted to delete a file, but it failed due to insufficient permissions. This usually happens when the file is in use or the user does not have the necessary rights to modify the file.

The root cause is that the current user or process lacks the required permissions to perform the unlink operation on the specified file. This can occur if the file is locked by another process or if the user does not have ownership or write permissions.

To fix this, ensure that the file is not being used by another process. Then, check the file permissions and modify them if necessary, or run the program with elevated privileges (e.g., as an administrator).
