My Storyline is taking forever to open. Is there a fix?

This started for me a few weeks ago after I did an update. Usually, my Storyline would take about a minute or so to open and be fully ready to use. But now it takes upwards of 5-10 minutes before it's ready, which is quite frustrating when I have work to do. It is currently fully updated. When I open it, I get the screen below (which looks different from how it used to look) and it just stays like that for the longest time. Not sure what the issue is or how to fix it. Appreciate any advice, thanks.
