Memory issue with my microSD card

Recently, my microSD card has developed a very weird issue where any new Folders will lose all their content upon ejecting the card from my computer.

If content is added to already existing folders, it stays after ejecting.

I’ve tried looking for issues with tools and commands, but everything says it is fine.

I’ve recently partitioned the SD card. 128gb Card with a 30gb partition.

Please help.
