Bug in Finder, it goes crazy when I type w in the search bar.

On Macos Monterey, 12 beta7, I typed the character w in the search bar of Finder, and after a few seconds (while I was looking for the other characters to type in) it went into a locked mad spin forever. Took me a while to find a way to force quit Finder. This seems to be a real bug to me. Has anyone experienced this? Is there a quick way to force quit Finder, some magic key combinations?
