LogicPro X 10.1.0 +Halion 5.1 crashing all the time

I don’t want to hijack this Logic-thread, but I have the problem that Halion 5 and other Steinberg plug-ins will crash Ableton when the AU version is loaded in a 64 bit Ableton project. Just in case it’s part of the same problem.

I’m on OS X 10.10.5
