Inspector stuck on "TagManager"

My inspector is somehow stuck on “TagManager.” I closed the tab and reopened it, etc. but it’s still stuck. Can someone help?

Make sure you have not accidentally locked the Inspector. See reference pictures below:

If it is locked, simply click on the lock icon to unlock. Alternatively you can right-click the Inspector tab and select lock from the context menu.
