ChatGPT Apps Broken in Safari?

Anyone else seeing this - AFAICT, all ChatGPT apps are broken in Safari (will not render) since a few days ago. Seeing this with my own unpublished apps but also published apps like Malwarebytes and ChatGPT Deep Research.

They have this console error:

[Error] SyntaxError: Can’t create duplicate variable: ‘SafariAppExtensionPage’ write P

Works in other browsers, seems Safari specific.
