Norton Private Browser opens in minimum size

Hi all.

i have recently had to uninstall and reinstall both Norton 360 and Norton Private Browser. Both are now working fine, except that when I click on the Norton Private Browser icon on the desktop the browser opens in minimum mode and I have to click the square in top right to maximise it to fill the screen apart from the taskbar at the bottom.

How can I get it to open in maximum mode please?

I am using version Version 130.0.27176.93 (Official Build) (64-bit)

OS is Windows 11 with 24H2 installed,.

Thanks.
