Pigments 4 freezes in Cubase 11

[uncle_heinz]

Hello,

i recently bought Pigments 4, cause I think it s a great synth. But everytime I open up an instance in Cubase it freezes the moment I touch a knob or browse for sounds.
In a complete empty project only one instance is running, if I add a second instance, it freezes. Sometimes Cubase is working again after some minutes of not touching anything. But in most cases i have to close Cubase via Taskmamager.
I m working on Windows 10, Intel i9-9900/3.6GHz 128GB Ram. Cubase 11

I have read some threads about similar issues, but couldnīt find any solutions.

Best

Here are some new made experiences. Pigments reveals the same issues in Ableton Live and also when I installed it on the PC in my second studio no more than one intance in an empty Cubase Project is running.
Arturia support offers just the advice to delete the prefs. WOW! That s the first thing  I did along with reinstallation and things.

Alrighty, Iīd solved the problem. I manualy installed the latest radeon driver, cause Windows allways told me, that latest version is already installed.
Now Pigments is working pretty fine.
