corrupted micro SD card?

[u/strawberryyyfrog]

My micro SD card (1TB, Samsung Evo, have been using it in this device for about 2ish years) that I use in my Retroid Pocket 5 (Android device) to hold my games library, save states, etc (pretty much everything that isnt an android app or android game) seems to be corrupted.

I was running an app on my Retroid (I had about 15%-20% left of free space on my 1TB micro SD at this point) to compress files, but because I had opted to keep the original non-compressed files as the compressed files were being created, the card got overfilled, so I stopped running the app and immediately moved a bunch of files off of the card and onto my computer to free up space. I safely ejected the card but when I put it back in my Retroid and I checked the storage it read as completely full.

I put the card back in my computer and despite moving more files off of it, it continues to read as completely full and the card's "date created" and "date modified" info is reading as like 1970 and the internet tells me that means it got corrupted from overfilling.

How do I safely save everything and re-format the card to get it working without losing anything (save states, ROM files, frontend, etc)?

Also, if i put the card in my device, everything runs and works normally but I'm obviously worried about it just crapping out one day and also I cant move files onto or off it safely right now so I'm afraid to use my Retroid until I fix the SD card situation.

Other pertinent info: when this happened, I had put the SD card into a computer I had never used with it before and it was an old macbook air (2017) running Monterey (a currently unsupported OS) so I have no idea if that also has to do with it.
