After installing UnityHub, it stopped at the place where UnityId was created with the white screen as below.
I can start Unity and I have no problem so far, but every time I start UnityHub, it comes out, and when I try to delete it, I am warned that the installation will be interrupted. Excuse me, but please tell me.

Applicable source code
What I tried

UnityId has been created.
Also, when you start Unity, you can create a project from UnityHub.
