Halion 6.4 Update Problem Mac

I have Problems to Update from 6.3 to the new Version 6.4!
I use Mac Mojave 10.14.6 and it´s the same Problem as Update from Cubase 10.5.10 to 10.5.12!
Every time the Installer brakes when it will install the content!

Steinberg Library Manager privileged helper has wrong version (-1.-1).

but I use the newest version of the library manager. I also have send a supportmail to steinberg and get a support ticket. but they cant help!

Someone have the same problems?

As attatchment i send a screenshot with the errror created when i try to install the update for cubase. halion is the same error!
