Activity tab shows High uncategorized time

But if I click on Category Builder, I see Unable to find bucket matching ‘aw-watcher-window_unknown’ (hostname filter set to ‘None’)

and down below
Common words in “Uncategorized” events
No words with significant duration. You’re good to go!

I encountered the same issue.
However, there is a workaround: go to the settings tab and under the “Categorization” chapter you’ll find a working link to the Category Builder.
