From you screenshot it does look like 32x32. I looked at it in Windows 11 Start11 on Windows 10 style. It still on 32x32 icon, it just get stretch out bigger in Windows 11 system.
Not really sure why the difference between Windows 10 vs Windows 11 system. To know more, I have forwarded your problem/question to Stardock Support Team for their assistance. Please keep an eye on this thread for any updates. We appreciate your feedback and patience. Thank you.
