Ok, VSCode is running and looking fine! The structure is restored again and the app is showing all Groups and Items correctly. The “only” problem is that they are not working. Also the sitemap in BasicUI does not show the list symbol but a “!” flag.
After checking in paper UI I realized, that the KNX-Binding got lost in the process (or at least I thought so; the binding was not visible on the bindings site). . . reinstalled it (I didn’t see that it was the 2.3.0 version), and the commands still won’t go thru to the KNX-Bus. . . in the log viewer I could see the openHAB commands but nothing happened on the hardware side (lights, switches, etc.). After I found out that the new version of the binding is different than the 1.12.0 version, I’ve uninstalled the 2.3.0 version agin and enabled the legacy bindings. By the way: why are installed legacy bindings not visble on the bindings site?
However everything is working again. Thank you guys!

Bert
