Windows 10 on pc desktop - Volume icon disappeared

[Apanta]

Hello,
as the title indicates, the volume icon on the taskbar has disappeared.
In reality this happens:
with the volume icon on the taskbar I enable the network icon, the volume icon disappears. If there is a network icon and I enable the volume icon, the network icon disappears. It's like there's no space to display both icons. In fact in turn one of the two icons moves to the right or left, but the other does not appear.
same thing if I try with other icons.
Only one appears in turn.
I tried by prompt as administrator the command: "sfc / scannow".
the answer is that there are no problems whatsoever.
Negative result, even trying to follow some discussion around the web.
Does anyone have any ideas about it?


Thanks in advance
