When I visit Drive on icloud.com, I get a message that "Drive has stopped responding."

When I visit Drive on iCloud.com, I get a message that "Drive has stopped responding." This occurs within seconds of clicking the drive widget on the main iCloud.com page.

I've tried this twice within the past week or so and the same thing happens. I have a lot of files in my iCloud Drive, but everything seems to be syncing fine from my multiple machines, so I'm curious about what's happening and if there's a resolution.

Any ideas what's going on?
