facing issue in the course taking too much time to page load

Hello, I am encountering an issue with the loading of the Storyline course page. I have uploaded the course on SCORM. The course was created using Storyline 360 in SCORM 1.2 version. I have attached a video showing where I am facing the issue of page loading into the course after clicking on the next button, and I am also attaching HAR files. Please help. Thanks in advance.
