I just updated "Upfront" now none of my pages load to edit.

I saw that an update was available for the "Upfront" theme upon logging into my site, so I upgraded the theme. Now, when I click "Upfront" to start making changes, 2 outcomes occur. 1. The loading page does not go away and the page does not load, stuck on loading screen. 2. The page completes the loading process yet comes up completely blank. Not sure if the update caused the issue or if there's already something being done to fix this issue.

Thanks!
