iTunes unexpected behavior when using search box

When I use iTunes to search for songs using the search field, when I type the characters f, e, s, v, c, a or h 50% of the time rather than the character being typed in the search box it attempts to open one of the menu items (file, edit, song, view, controls, account, help) which is massively frustrating when trying to create a playlist of songs and trying to search your song list.

There was another post from 2013 about the same thing that I found, it wouldn't let me update that post so I created a new one, but the response from Apple was to uninstall and reinstall, I've done this and it still does it. I think it is a bug with iTunes?

I'm using iTunes 64 v12.7.3.46 on Windows 10.
