Camera reads memory card but computer wont.?

I have a memory card and my camera reads, records, etc on it just fine. But when I put it in my computer to try to download the videos/photos from it, the folder for it has an x (like, using Windows 10, under Network locations, it lists the memory card and the photo has an x next to it). When I try to open it I get his message: "An error occurred while reconnecting Z: to (memory card). Microsoft Windows Network: The network path was not found. This connection has not been restored)." I double check to make sure it wasn t locked (and it isnt) and I ll re-put it in. After a couple tries (every once in a while) the auto-download photo prompt will pop up and read the files. I select the photos/videos I want to download like normal and hit download, and then I ll get an error message telling me to connect a device and try again. It just suddenly stops reading it. I really need the photos/videos off this card.
