Windows 10: Windows 11 shortcut icons white - icon cache fix does not work

I have a lot of icons that worked in Windows 10, but not 11. However, if I use them as desktop icons, i.e., set in settings, then they work. The phrase "the OS cannot load the icons" seems pertinent, however I cannot find anywhere specifications for Windows 11 icons. The icons were created with iconfx . They are 256x256, colour, some with transparency. Deleting and recreating the icon cache makes no difference. I cannot find any documentation about specs for Windows 11 icons.

Blank shortcut icon GPU-Z

Sometime ago I installed the latest version of GPU-Z, started up my laptop the next day and noticed that the GPU-Z shortcut icon was white, I tried to find the icon in GPU-Z.exe but it said: "GPU-Z.exe contains no icons".
I hope I the icon will return in the next version.

It's not fixed, today my GPU-Z icon is a blank shortcut icon again..
And it says GPU-Z.exe does not contain an icon

I know I am quite late but as I was scrolling through I saw this post which happened to one of friend too. This sometimes happens with Windows. Usually a reboot will solve the problem. However if this doesn't, try setting the icon for the shortcut(right-click pinned icon, right-click program, left-click properties, select "change icon...") or refreshing it by switching to a different icon, applying it, and then reverting back to the original icon. Remove the shortcut from the taskbar and replace it with the start menu shortcut or simply drag the .exe file to the taskbar.
