The error message you are encountering, RuntimeError: Proxy error(FileLoadException): The file cannot be opened. It might have unsupported format or be corrupted. ---> InvalidCastException: Unable to cast object of type '_GCg' to type '_z1', suggests that the PDF file you are trying to convert may not be supported or could be corrupted.

To troubleshoot this issue, consider the following steps:

  1. Check the PDF File: Ensure that the PDF file (ME19-4716_P8.pdf) is not corrupted. You can try opening it with a standard PDF viewer to confirm that it displays correctly.

  2. Use Load Options: When loading the PDF document, you can specify PdfLoadOptions to control how the PDF is processed. This can help in cases where the PDF has specific characteristics that need to be handled differently. For example, you can set properties like PageCount, PageIndex, and Password if the document is password-protected.

    Here’s a code snippet demonstrating how to use PdfLoadOptions:

    import aspose.words as aw
from aspose.words import PdfLoadOptions

# Specify load options
load_options = PdfLoadOptions()
# Set any necessary options here, e.g., load a specific page
# load_options.PageCount = 1  # Load only the first page

# Load the document
document = aw.Document("ME19-4716_P8.pdf", load_options)
# Save to DOCX format
document.save("ME19-4716_P8.docx")

  3. Supported Formats: Ensure that the PDF file is in a format that Aspose.Words can handle. Aspose.Words supports various document formats, including PDF, but there may be limitations based on the content of the PDF.

  4. Update Aspose.Words: If you are using an older version of Aspose.Words, consider updating to the latest version, as newer versions may have improved support for PDF files and bug fixes.

If the issue persists after trying these steps, you may want to reach out to Aspose support with details about the PDF file and the specific code you are using for further assistance.
