    The issue is back in 2020.3.32f1, but somewhat different. ObjectHideFlags is set to 1 in my files and the inspector shows nearly nothing, but in comparison with setting the ObjectHideFlags to 3 it shows the name of the state, the tag and hovering over where the supposed Speed or Cycle Offset should be changes the cursor as it should. Also Transitions cannot be made from states which have other transitions leading to them.

    I'm currently having this issue on 2020.3.32f1. Tried it in multiple projects. And the workaround mentioned (m_ObjectHideFlags: 1) didn't work for me. It was already set to 1.

    I have found that when a blend tree is duplicated it is written into the controller file as:
    m_ObjectHideFlags: 3

    Editing the controller in a text editor and changing it to:
    m_ObjectHideFlags: 1

    fixes the issue and the UI draws again.
