NVME Drive Problem?

Hey, my NVME drive was working fine today until all of a sudden I couldn't open a game that was on the drive. I got the "an error occured while launching this game disk write error" so I went to clear the download cache for that drive. Now, File explorer doesn't pick up the drive but when I went to the BIOS the drive was there. When I go to download a game on steam, steam still picks up the drive. Disk management doesn't pick it up either. What's going on and how do I fix this? Thanks
