I cannot open any of the documents I had on LibreOffice Writer stationery? They come up as "Not responding". Can anyone help me get back the 100's of documents I have done please?

I have suddenly been unable to open any of the LibreOfficeWriter documents that I have hundreds of on my Windows 10 computer and have no idea what has caused the problem or, worse, how to rectify it. I even tried downloading LibreOffice 6 but even that isn’t responding. Can you help please?

Can you see the files from windows explorer?
