• Extract the zip file; check the 'imsmanifest.xml' or 'metadata.xml'; and find '<lom'. 
• Remove any of these references in the files and Save.
• Re-compress to .zip format using a tool such as WinRAR.

Note: Ensure that all files/folders are selected for re-compression, not the extracted SCORM folder.

• Attempt to upload the SCORM package again.
