Invalid auth credentials during setup on macOS, SSO enabled, ADFS

Hello,

We're seeing issues with signing in during install on macOS. After entering the email adress, we immediately get error -338 (ERR_INVALID_AUTH_CREDENTIALS) before even entering a password. I do notice that a sign in window for our ADFS pops upp for a split second before dissapearing and showing the error. I had to record the screen to be able to get a screenshot.

Any ideas? On Windows this seems to work fine, and im also able so sign in with SSO in the browser on this mac.

macOS 15.6

Matlab R2025a

edit* On a non-AD bound PC, the same issue occurs, im not presented with an option to provide any login information before it fails. On the PC i dont see any prompt flash by either, just error immediately.
