(Selective) Freezing at Login

Have a Macbook Air, running Sonoma 14.0. I login with my email and password, and get to the “login complete” screen, where it simply freezes. The cursor shows the spinning color wheel when I hover over the zwift screen. I’ve deleted the app and reinstalled it, to no avail.

However, I also signed in as a new identity, and the app ran smoothly. Also, ci can run zwift on my iPad and iPhone.

How do I get the app to run on the MacBook as it always has?
