WINDOWS 11 TASKBAR SYSTEM TRAY ICONS KEEP MOVING OUT OF HIDDEN MENU

Hi all

I have been setting up a new laptop with Windows 11 25H2 Build 26200.6584 and when I move system tray icons to the hiden menu, about 40 or 50 seconds later windows unhides them and there appear back on the task bar.

It is driving me mad as the task bar looks to cluttered.

If it is a known bug, is there a fix for this?

According to google searches, this is a known bug and none of the suggested fixes work..

I have tried:

Re-arrange Icons via Drag-and-Drop.

Restart Windows Explorer.

Disable Fast Startup.

Rebuild the Icon Cache using CMD window as admin

I tried to delete the icon cache so windows had to rebuild it but 

taskkill /IM explorer.exe /F
del /A:H "%localappdata%\Microsoft\Windows\Explorer\iconcache*"
start explorer.exe

but it gave the error below.
