I've noticed this issue yesterday. When I try to search something in my File Explorer it looks like it's searching but the green bar seems to go on forever. I left it up for an hour and it was still searching when I came back. I even tried to look for files that I knew were on my computer and got the same result. I tried restarting File Explorer with the Taskbar and it didn't work.
I would be grateful for any help you guys might give me.
