Box will not open on Amazon Workspace Machine

I have been using Amazon Workspace to remote into a machine, and have been successfully using Box on the web browser on that machine for months. Today - it will not load past the login screen.

I downloaded the Box app and that will also not load past the 2FA login screen - the app closes at that point.

I have successfully used both the App and the web browser with that same box account on a separate machine. At a loss for what to try next to get it to work again on the AWS machine.
