27" iMac w/Retina HS Not Loading Past Tavern Doors

Hello. I am running macOS Catalina 10.15.4 on a 27" iMac with Retina 5K display. I have tried uninstalling, and reinstalling HS, restoring games settings, etc. HS will launch in a small window, the logo will appear, and I’ll see the social icon on the bottom left, and settings logo on the bottom right. The cursor turns into a hand when I go over the HS window. BUT it won’t go past this screen with the HS logo. What else can I do to resolve this?

I also cant download Hearthstone at all for this version of the OS on my Macbook Pro. Please can someone link the right version that will work with this OS?
