Patient-specific fiber tracts inside the popup menu under
Include structural (dMRI) connectivity. But it’s missing now, isn’t it? What’s the output of

Maybe you can also try to install the hotfix from here, which would update your lead-dbs to the development version. And see if the error still occurs. If so, you may send me some screenshots via Slack (join our Slack group here if you are not in it yet).
