Sso / problems logging in?

I have not been able to log in for days on my sso login and honestly do not know what the problem is, the launcher was updated a few weeks ago with me, I could log in with this launcher then 2 days until they said then as soon as I wanted to log in: "Something went wrong, try again." I contacted Sso but they did not help me. I was neither locked nor has my laptop problems, who has any idea why that is? So when reinstalling is not.

Did you delete the leftover folder by hand when uninstalling?
