I reopened the bug. I don’t know enough details to give you more hints. I think there could be something different because if it were the case for all mac users, there would be much more reports. Perhaps try with a different server, if that happens there as well, so you can link it to the client only or if the server is possibly involved as well.
Question is as well, do you use two-factor-authentication. After a login, there should be an app password, does this app password still exist (security settings on your personal settings page)?
It’s strange there are a few people complaining. In the bug report it was originally a client version 3.4.x on MacOS Monterey (12.2.1). But the problem appears on different platforms (Linux and Windows). Some clients since then seem to have solved the issue for some but not all. Also to consider is that there are probably a lot of users that don’t have this problem.
Unfortunately there are no instructions how to dig deeper. In case you have two very similar systems where one has the problem and one hasn’t, that could be interesting.
Since the problem exists on different platforms and was solved for some, you might just share a symptom but not the same problem. If you have more specific errors from the logs where it shows why it can’t authenticate … unfortunately I don’t know the internals for this process to help you out.
