Two Finder processes are open. Neither works. What gives?
Try restarting the LaunchServices database. Launch the Terminal app (Cmd+Space, "Terminal"), and type in

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user


Then quit Terminal, restart your mac, and let us know if that fixed it.
