Halion 5 Serious Error with Disabled Tracks

I can’t figure this one out. I have 2 systems. One system works fine. The other has a serious error when I do the following.

  1. Insert 1 instance of Halion 5 into blank session via instrument track.
  2. Disable that track.
  3. Now enable that track.
  4. Disable that track again.
  5. Enable that track again… SERIOUS ERROR

Once I get the serious error if I try to load another instance of Halion 5 the serious error happens upon trying to load it.

Here’a the strange part…if I load 2 instances of Halion 5 and disable one of them I can disable/enable all I want with no error.

Crash log attached.

Here is the crash log text…
