Content Missing in Halion Sonic SE3

New Cubase 10 user here. Just installed Cubase 10 Pro and so far I’m liking it very much. Anyhow I can’t get Halion content to show to Load tab. Only one which is my own setup will show at the content window. I reinstalled all content from Cubase 10 but issue remains. When I try to rescan library then content quickly flash and I see text there but then window become blank again.

Here is the screenshot how my Halion window looks like normally.

Problem solved by uninstalling all Steinberg related applications and manually cleaning registry. Then downloaded all content and reinstalled all.
