I have an SD card that worked and still does, for example with music.
I can access the SD card from my windows computer and everything looks normal.
However the camera-app which saved videos and photos on the sd card suddenly created a failed jpg file (mostly stripes) and afterwards no photo is saved/created anymore and videos have size 0.
If I change the photo location to internal card everything works again. A restart of the system did not change anything.
The SD-card is 90% empty.
can you try to reformat the sd card?
