Can some dev look into these dualcore desynch freezes/crashes?

Did you try reinstalling Windows. It really does sound like you have something broken on your end, not our end.

Also: "Instead I can reproduce the crash right away, for example spinning the camera and saving states one after another." Save states can still cause issues, especially in the scenario you described.

Also, your CPU is not great for Dolphin (but you know that when you said there's slowdowns)
