Corrupt .story file

The issue you're experiencing with your Articulate Storyline (.story) file appears to be related to its size, which is quite large at approximately 4.65 GB. Many systems, including Learning Management Systems (LMS) and software applications like Articulate Storyline, have limitations on the size of files they can handle. Transmitting such large files, especially via platforms like WeTransfer, can occasionally lead to issues such as corruption or incomplete downloads due to network instability or timeout errors Kynect
Verify the maximum file size limitations for both the LMS where the SCORM files are uploaded and the Articulate Storyline software where the .story files are opened. If possible, consider breaking down the project into smaller, more manageable modules or chunks. Use file compression techniques to reduce the overall size of the .story file before transferring it. This can be done using tools like WinZip, 7-Zip, or macOS's built-in compression utility.  Instead of WeTransfer, consider using alternative file transfer methods that may be more robust with large files, such as FTP (File Transfer Protocol) or cloud storage solutions that offer direct sharing links.
