MacOS – Changing the default folder for opening a new Finder tab or window in macOS High Sierra

When I press ⌘+T or ⌘+N in Finder to open a new tab or window, for some reason it always starts in this folder:

/System/Library/CoreServices/Finder.app/Contents/Resources/MyLibraries/myDocuments.cannedSearch

I know on other macOS systems it typically opens in the user's Home folder.

It makes no difference whether I already have other windows or tabs open, or if I close everything and then open a fresh new window, the above always happens.

Is there some way I can change this? Is there a configuration setting somewhere for a default folder for any new Finder window?

P.S. I'm using macOS High Sierra 10.13.6.
