Well I was unable to reproduce the issue over here when you sent me the file, and your crash minidump showed the issue happening in the PhoenixFD dlr file...so your recourse would be to follow up with Chaos as I am unable to debug the plugins of other developers.
A potential workaround would be to change your PhoenixFD settings to export VDB files instead of AUR files, and then load the resulting VDB files into a tyFlow Birth VDB operator (file mode, with your PhoenixFD container assigned as the transform node), and use the VDB Force operator to drive your particles that way instead. That way you would avoid the use of the PhoenixFD loader to read the cache data into tyFlow and also potentially avoid whatever issue is causing the crash.
