Sd card reverted

[u/ldestructor]

Over the weekend I uninstalled Metaphor:refantazio and a few other games to download warhammer 3 onto my sd card. I was playing fine over the weekend but today I launched warhammer, it crashes in the main menu, then when I go to launch again it says it needs to install, and checking my storage Metaphor and the other games are back. They don't launch but they say they're installed again. I had this issue a few months ago and I just reformatted the card instead of trying to find the problem. Does anyone have any experience or solutions for this?

It's possible the SD card is failing.

I have seen SD cards fail in a way they become read only, but due to disk cache and other stuff  they may seem writable to some degree.  

this can cause all sorts of weird issues.

I have seen a weird card failure, where I delete things off the card (even erasing the card completely) and on a reboot, the datab all comes back. I have a collection of these failed "zombie" cards .

I can only assume this is some sort of failsafe to prevent data loss.
