stream: Union[BufferedReader, BytesIO] = open(path_or_fp, "rb") PermissionError: [Errno 13] Permission denied: '.'

This error occurs when the program is attempting to open a file or directory for reading, but the user does not have the necessary permissions to access the file.

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

1. Check if the file or directory is being used by another program. If so, close the program and try again.

2. Check if the file or directory has the correct permissions. Make sure that the user has read access to the file or directory.

3. If the file or directory is located in a protected system folder, run the program as an administrator.

4. If the file or directory is located on a network drive, check if the network connection is stable and the user has the necessary permissions to access the file or directory.

Once you have resolved the permission issue, you should be able to open the file or directory for reading without any errors.
