ChatGPT macOS app unusable on Tahoe? (Hmm… something went wrong)

Is anyone else having issues with the ChatGPT macOS app on macOS Tahoe?

For me it’s basically unusable:

  • Every prompt gives “Hmm… something went wrong”

  • If I reset the app, it finishes loading the response , then it breaks again when I try to send another one

  • Happens in every chat

Web and iOS work fine on the same account/network, so it seems like just the Mac app.

Also seeing some weird logs when launching from Terminal (duplicate class + a ton of Statsig errors), not sure if related.

Just trying to see if this is happening to others or if it’s something on my setup.
