SD card randomly showing no images

I have a Fujifilm xs20 and I was taking pictures with it yesterday perfectly fine and was able to look through them and everything. This morning I tried to plug in the SD card to my reader, and I got the no images icon, which has never happened before. I plugged the Fujifilm back into my camera and the pictures showed up again, perfectly fine. I put it back in the reader, same issue. then I put it back into my Fujifilm one last time and this time there was no photos. I didn’t press any buttons or anything so I plugged it into my laptop, and I saw that it was reading, but when I looked at the folders, there was zero data left in them. I don’t know how. Has this happened to anyone and is there any fix for it? i’m mainly trying to figure out whether this sounds like SD card corruption, a failing card reader, or if the files may still be recoverable.
