I installed the latest download in two separate DNN installs, and I had the same issue -- the File Browser interface does not display correctly.
It appears the latest download is missing a file:
Providers\HtmlEditorProviders\CKEditor\Browser\Browser.comb.min.css
Once I copied that file over from the default DNNConnect.CKE editor, it all appears to be working fine again.
