Yes, I found the solution by myself.
Problem was related to a built-in Addin (developed by Microsoft but.....not signed.....).
Disabled the faulty addin (EURO CURRENCY TOOL) and now it's fixed.

Probably, Excel is using the file that includes a VBA script or something.
What happens if you delete contents of the folder "C:\Users\XXX\AppData\Local\Microsoft\Windows\InetCache\Content.MSO\
Verify that there is not important files before deleting.
You can also add an exclusion to Windows Defender.
It can be a file, folder, file type or process.

Hello,
I've checked inside the folder, it's empty - and when I start Excel creates some .tmp files.
Also the problem isn't related to a XLXS file, because I have this behavoir also If I only start EXCEL.
