Pianoverse Buffer Problem

[isikaka]

hello evernyone, i've just bought Pianoverse but after playing a few notes or chords each time , no longer will be any notes to hear.. I've never had any issue with other plugins like this..
Midi trigger does work , even you can trigger with mouse definetly.. but aint no sound at all..

I've tried different buffer and resolution options..

My setup is: Imac 2020 inteli9 ssd drive / SONOMA 14.6.1
Apollo twin X for mac.

Any idea pls?

i can literally tell it like , if repeat playing notes 25 30 touches and no sounds after that.. u have to close the software and re open.. and again same

for an update, if i lower down to 48000 sample rate and 512 buffer it lets me play only sometimes pops cracks stutters .. still unaccteptable, i really dont have any turst upon apollo twin or my mac anymore.. but this issue only faced with this plugin.. the last addtion i can do is that i got 8 gb rams , but while keyscape doesnt have any issue with it , whats wrong with pianoverse.. i fall in love with hammers , brightness all perfect but what the hell man.. i am still waiting for an help from ticket..
