Arturia Pigments 3 crash backtrace

Pigments 3 is a VST synthesizer plugin used in music production. It can be
found at:

https://www.arturia.com/products/analog-classics/pigments#en

and it installs successfully in Wine via Arturia's Software Center, which is
available at the top of this list:

Pigments seems to be working well, with one significant flaw - if you mouse
over the volume control knob icon (in the upper right corner of the UI), the
app freezes/crashes. I believe this is the only thing preventing this synth
plugin from working flawlessly.

I'll attach a backtrace of the crash report. I'm running the latest Wine
Staging (6.8) on an Ubuntu 20.04 system with kernel 5.9.16-050916-generic from
Ubuntu's kernel PPA.
