Blank screen in "new" AI Foundry and unable to go back to "classic" view

Hi, I toggled on the "new" AI foundry experience. But it just gives me a blank page. 

I cannot disable it and go back to the old view though. 

When I go to https://ai.azure.com/ it takes me to the "nextgen" page (e.g. https://ai.azure.com/nextgen/?wsid=%2Fsubscriptions...)

Removing "nextgen" from the URL just redirects me back to the "nextgen" version.

This also happens to my colleague, and we can't use the Foundry.

Can you help?
