CC3 works fine. cc4 is suspended.

For my computer;

open CC4
close CC4
in task manager CharacterCreator.exe is suspended. I have to restart my computer to release suspended app and memory.

My workaround;
stop windows audio service
open CC4
close CC4
start windows audio service
in task manager CharacterCreator.exe is NOT suspended

I tried to
uninstall all reallusion products and reinstall.
run as administrator
using different account in the same computer
disable exclusive mode for all audio input and output device
