Crash with expanse-5 by Acoustica

Hello! I am testing the new Prophet Style Synth expanse-5 from Acoustica, witch sound phenomenal. Unfortunately it’s crashing most of the time I send a program change message. I already have a support ticket from Acoustica, but since this doesn’t happen in MainStage I thought maybe it might also be good to post this here. Same issue with VST3 / AU and different buffer settings.

Hardware:
MacBook Air M1 8 Core, 8GB Ram, Arturia Keylab 61 MK1
Software:
Gig Performer 5.1.1, XPST au 3.0.5 build 1

how do you send the PC message to the plugin?
