Anything DIY to be tried with dead (not recognized at all) MicroSD card?

This morning I picked up my old smartphone with a notification saying not to remove SD card without ejecting.

Turns out it just died overnight.

I tried putting it into some other devices, and they also don't see anything. It did incorrectly show up as "127MB disk" on 2 different SD card readers when I sprayed it with liquid butane from air duster can, but that's just something like -1°C as far as I can find, so pretty lame.

Anyway, I can't find the backup anywhere, aside from a partial one from 2020. It's not worth spending money on, but perhaps some effort it would.

I seem to have all but 1 apks backed up on a DVD, a few photos from 2020, root/unroot zips and CWM recovery, and modified cacerts.bks with newer root certificates, so what's missing is Monte Gallery apk, and few unknown photos, and perhaps some app data.

Ideas?
