It was working in iOS 13 beta 2.
All the adapters mentioned in this thread are now not working:

And to confirm my suspicions I used 3uTools again, to reinstall iOS 13 beta 2.
Now ALL adapters are working, the Belkin + Apple and also the USB camera 3 adapter and Anker.
I submitted a bug report, however was unable to trigger a sysdiagnose. It's not working for the iPAD, I waited and waited and waited and no sign of it.
Luckly I was able to return to beta 2.
