Windows Search not working

Question

Just recently, no changes to windows, my search is not working. Usually when you click on start then begin typing a list of apps appear - that has stopped. Also after clicking on the magnifying glass when the "Type here to search" appears, I cant type anything.
Looking at Event viewer I get two errors every time I try and search - shown below.
Any ideas?
