Hello, for using the UI Builder version preview.17 you need Unity 2020.3.12f1 or newer. Also there’s a new version out as of yesterday (preview.18) that we’re recommending 2020.3.15f1 or newer.

You need to update your Unity installation in order to use newer versions of the UI Builder package. We also suggest using the UI Toolkit package of the same version number.
