Crazy Windows 10 got this issue less than 24h ago for all Windows 10 PCs. This Windows 10 Search supposed to be local program and file search is somehow connected with Bing Search Engine and Microsoft Server. Although many people and I have disable all data feedback/communication to the Microsoft, this Search Feature on the Windows 10 local PC stopped working as of Fed 6, 2020 because MS Servers somewhere have problems…. This makes no sense. I think Microsoft has been stealing data from the PC users… To fix this Search Feature working again on Windows 10 PCs, follow the instruction on this link https://www.howtogeek.com/224159/how-to-disable-bing-in-the-windows-10-start-menu/.
