Cannot Start New Campaigns

For about the past two days, attempting to start a new campaign in any world gives me the following error upon trying to load the pre-campaign setup lobby:

“Error: Loading chunk 5693 failed.”

This results in campaigns being stuck in the “finish setup” phase since I can’t get to the final stage of the setup, where you’d normally see all the slots to invite other players and have the button to actually start the campaign. For the record, I can use all other parts of the website, including continuing to play in existing campaigns, just fine. I simply cannot start new ones.

This error occurs in both the mobile app and in desktop browser; tested in Firefox and Chrome, after emptying cache, and in private browsing windows.

Below is a screenshot of the full error screen.

Steps to reproduce: log in, click play on any campaign, then select or create a character.
