Scorm File Issue or LMS Issues??

I was just concerned as to why, for the first time, a "Error" appeared after I clicked the submit button after uploading the scorm file 1.2 to the LMS. This course is currently required to be upload online to the LMS as part of the act of learning, I tried uploading another scorm file, but I kept getting the same error and only the SCORM 1.2 package is properly uploading in the LMS. Could you please provide additional recommendations?

I've already checked, and there are no issues with publishing the SCORM file. When I first start my first project with scorm file size 50MB, we did not encountered any issues/bugs. However, now that we're on our third project with a larger file size 560MB,
I suspect the issue might be related to the data in the LMS system.

Note:
I’ve already spoken with LMS admin, and he proposed trying to upload my SCORM file 1.2, but he still getting the same error I encountered.  I'm a little confused. I asked about the LMS SCORM file size limit, and he mentioned it's 1GB. So, what happened???

1st project - 50MB - success
2nd project - 150 MB - success
3rd project - 560 MB - failed to upload

My work has a larger file size because all of my assets were mp4 file that I downloaded from synthesia and included many images and infographics.
