Sudden problem with the BIAB VST DAW Plugin. Same happens in all my DAW - Logic, Reason and Cubase. Only changes I’ve made before the problem appeared was installing Steinberg Hailion 7.
Loading and using the BIAB plugin works ok. It’s only when I’m trying to open an SGU from MySongs in the VST DAW Plugin, that the DAW crasches. I’m on MacOS 12.6.3 and my BIAB version is 2022 (611) 64 bit application - Rosetta mode
Support advised me to rebuild style picker inside the plug-in. Didn’t help.

Looking at Steinberg's Halion 7 it is available in AAX, AU and VST3 formats. Of those three formats I know Band-in-a-Box will not work with VST3 plugins. So if you designated the VST3 version of Halion 7 as your Band-in-a-Box midi soft synth it may not work.

Verify that you are running build 4.8.15 of the DAW plugin by clicking on File | About. If you do not, download and install the build 611 patch from here:
