Import Midi Files do not map to Halion Sonic - help

Hello community,
On my (new) Laptop I can not set Cubase 13 LE to map midi import to Halion Sonic (in the preferences).
grafik. I have uninstalled Cubase, Halion Sonic SE (and the content) and Groove Agent SE (and the content). Then re-installed again with the Donwload Manager.
No change - still missing.
On my main production PC (where I have Cubase PRO installed), this shows up and maps midi file tracks correctly to Halion Sonic.
grafik
All systems in Windows 11
If anyone knows the fix, please help.
Thanks and tyke care
